About this episode

The hosts debate whether TEMU-style performance parts belong on a real car, using “real vs. fake” examples across turbos, sensors, wheels, and fuel-system components. They argue unbranded “white box” parts can be hit-or-miss, with electronics and sensors being especially failure-prone, and that cheap turbo setups can create dangerous outcomes like interference or seal failure. They also question how social media makes short-term dyno/track results look convincing while long-term reliability gets ignored.

Term

turbo kit

"[14.2s] He's putting together a budget bill for a contest, I think it's what Cladest McFarland, [18.8s] and he basically put together a swap, turbo kit, the whole thing for like five grand. [24.6s] Oh my damn, that's super cheap. How do you do that?"

A turbo kit is a set of parts that lets you add a turbo to your car. It’s meant to boost the engine’s power, but it has to be installed and tuned correctly to work safely.

Term

aftermarket

"[39.9s] plays out, like once this thing releases, once it actually shows up. [44.3s] See, that's the problem when we get into some of these aftermarket... [50.9s] After aftermarket companies, let's say."

Aftermarket just means parts that aren’t made by the car’s original manufacturer. They can be great, but quality and fit can vary a lot depending on who makes them.

Term

gaskets

"[57.2s] You know, yes, the parts might be the same. [62.3s] You know, yes, they might be using the same gaskets, little things, this, that, the other thing. [67.5s] It's all coming from the same place, let's say."

Gaskets are the seal(s) that stop fluids or gases from leaking where parts connect. With performance parts, the gasket has to handle heat and pressure, so quality matters.

Term

white box

"[73.6s] Do you have experience with the product? [77.9s] Things like that kind of start to scare me, because coming from inside the industry, [81.5s] we did get a lot of parts that were, let's say, not branded or white box or whatever [87.1s] you want to call it."

“White box” means a part is sold without a well-known brand name on it. Since it may come from different sources, you can’t always count on the same quality or reliability.

Term

electronics

"[87.1s] you want to call it. [88.8s] And it was hit or miss. [92.7s] Electronics was always a problem."

In aftermarket and swap/turbo projects, electronics can include sensors, wiring, and engine control components that must communicate correctly with the car’s systems. The host’s point is that electronics are often where unbranded or low-cost parts fail—through wrong specs, poor shielding, or inconsistent behavior.

Term

flex sensor

"Flex sensor, you know, no-name flex sensors scare me, because they would just stop reading"

A flex sensor is a small electronic part that detects how much something is bending. On a car, it can be used to measure movement so the car can respond correctly.

Term

ethanol

"in the middle of, you know, running ethanol through the car and they would default and"

Ethanol is a type of fuel alcohol that can be mixed with gasoline. Because it behaves differently than regular gas, the car may need a different tune to run safely.

Term

tune

"they would default and your tune would go crazy and the car would try to eat itself."

A “tune” is the car’s settings for how it runs—like how it meters fuel and timing. If something important stops working, the car can switch to backup settings that may not match the tune you paid for.

Term

valving

"There might be proprietary agreements in place with that manufacturer where they can't use some of the technology that is in say, you know, uh, valving for your shocks, let's say."

Valving is the inside “flow control” in a shock absorber. It controls how the shock resists movement, which changes how the car rides and handles.

Term

shocks

"some of the technology that is in say, you know, uh, valving for your shocks, let's say."

Shocks are the parts that help control bouncing and keep the tires in contact with the road. Different shock designs can feel very different.

Term

knockoff

"Like this, this goes back years and years with knockoff companies, uh, doing electronics, [218.4s] doing, uh, suspension, um, you know, even, even simpler stuff like, like a header or,"

A knockoff is a fake version of a car part. It might look right, but it may not be made to the same safety standards as the real one.

Term

suspension

"Like this, this goes back years and years with knockoff companies, uh, doing electronics, [218.4s] doing, uh, suspension, um, you know, even, even simpler stuff like, like a header or,"

Suspension is what helps the car ride smoothly and stay stable over bumps. If suspension parts are fake or low quality, the car can handle unpredictably.

Term

header

"doing, uh, suspension, um, you know, even, even simpler stuff like, like a header or, [224.6s] or like an intake, you know, something, something basic like that."

A header is part of the exhaust system near the engine that helps gases flow out. If it’s low quality, it can leak or wear out faster.

Term

intake

"or like an intake, you know, something, something basic like that. [228.0s] The question is why now is it so much more acceptable to, to do this type of thing compared"

An intake is how the engine gets air. If an intake part is fake or poorly made, it may not fit right or may not filter air well.

Concept

skirting around

"Now it's like, it's almost like people feel as if they're sticking it to the men by kind [243.2s] of going or skirting around and going with the cheaper option."

The host means people are trying to get the benefits of the real thing without paying for it. They’re treating the cheaper option like a workaround.

Term

center caps

"They even have like the, the center caps are exact copies. [281.6s] That's kind of their, their, um, their proof that this stuff is just as good."

Center caps are the pieces you see in the middle of many wheels. Knockoffs may copy them to look identical, but that doesn’t guarantee the wheel is actually safe.

Term

eBay turbos

"And I know before when they were still based out of Colorado, they were doing like eBay turbos. They would call them eBay turbos, right."

They mean turbochargers bought from an online marketplace (like eBay) instead of a reputable performance brand. The point is that these can be hit-or-miss and may fail sooner than you’d expect.

Concept

R and D

"And you know, who knows where those came from and what kind of R and D was put into them, but they were working right there."

R and D means research and development—basically the testing and engineering that goes into making sure a part works reliably. They’re implying the parts may not have had much of that.

Term

service item

"So funny enough, I had a eBay turbo multiple times on the SRT four and it ended up being a service item more or less."

They’re saying the turbo ended up being something they had to keep fixing or replacing. Instead of being a permanent upgrade, it turned into a recurring problem.

Term

seals

"Like I was like, all right, the seals going to blow in 10,000 miles. Let's say it wasn't that, but whatever."

They’re talking about the seals inside the turbo that keep oil and exhaust from leaking. If the seals wear out, the turbo can start failing and you may need to replace parts sooner.

Car

VQ community

"So prime example, turbo kits are big in the VQ community. A lot of these guys do like a front mounted single kind of similar to the treadstone kit"

“VQ” is Nissan’s engine family that a lot of car tuners like. So the “VQ community” is basically the group of people who modify Nissan cars with those engines.

Term

front mounted single

"A lot of these guys do like a front mounted single kind of similar to the treadstone kit that came out years ago."

This means the car uses one turbo, and it’s mounted toward the front of the engine bay. The piping then routes exhaust and boost to the engine in a specific way.

Brand

treadstone kit

"A lot of these guys do like a front mounted single kind of similar to the treadstone kit that came out years ago."

They’re talking about a specific turbo kit brand that’s been engineered to fit and function correctly. The point is that knockoffs may not match the original’s fit and quality.

Term

interference issues

"So the turbo doesn't sit exactly right. So now you're at interference issues and then it's those small little nuances"

“Interference” means parts can hit each other inside the engine. If the turbo kit parts don’t fit correctly, it can mess up clearances and lead to a serious damage risk.

Term

3D scans

"there's a massive R&D push behind it versus somebody goes in 3D scans a product and just replicates it. There's a difference there."

This is copying a part by scanning its shape into a computer. The host is saying that copying the shape doesn’t automatically mean the part will fit and work safely like the original.

Part

turbo manifolds

"And even down to like the quality control of the product itself, we had turbo manifolds that had, I was, you know, the turbo manifolds had like welding slag still on the inside"

A turbo manifold is the part that collects exhaust gas from the engine and feeds it into the turbo. If it’s poorly made, debris or defects inside can cause problems once everything heats up.

Term

quality control

"And even down to like the quality control of the product itself, we had turbo manifolds that had, I was, you know, the turbo manifolds had like welding slag still on the inside"

Quality control means inspecting parts to make sure they’re made correctly. The host is saying the copied turbo manifolds weren’t properly checked before shipping.

Term

welding slag

"the turbo manifolds had like welding slag still on the inside from where they would like tack it with a MIG welder"

Welding slag is residue left over from welding. If it’s trapped inside a turbo part, it can come loose when it gets hot and cause damage or flow problems.

Term

MIG welder

"from where they would like tack it with a MIG welder before they would go through and like actually weld it with a TIG weld."

MIG welding is a common welding method that uses a wire and gas to make the weld. The host is saying the knockoff parts were tacked and not finished/cleaned properly.

Term

TIG weld

"before they would go through and like actually weld it with a TIG weld. And you would see like a piece of welding wire sticking out"

TIG welding is a more precise welding method that typically produces cleaner, higher-quality welds. The host is saying the real process should use TIG welding, but the knockoffs didn’t do it right.

Term

machining

"You can buy the highest quality manifold and it doesn't, something was off with the machining. [562.5s] You got a bad batch, whatever it is, the difference being you can typically go back to that manufacturer"

Machining is how parts are made with precise cutting and shaping. If the machining isn’t accurate, the part may not fit right or work correctly.

Term

fit right

"You got a bad batch, whatever it is, the difference being you can typically go back to that manufacturer [568.1s] and be like, hey man, this thing doesn't fit right. [570.2s] And then they go, oh, our bad."

“Fit right” means the part lines up correctly on the car. If it doesn’t, it can be hard to install and may not work properly.

Term

swap it out

"And then they go, oh, our bad. [571.6s] Send it back, we'll swap it out or you order the rock. [575.0s] Whatever it is, whereas with like, getting off EB or something, good luck."

“Swap it out” means they replace the bad part with a new one. Legit sellers usually make it easier to fix problems if something is defective.

Term

EB

"Send it back, we'll swap it out or you order the rock. [575.0s] Whatever it is, whereas with like, getting off EB or something, good luck. [579.7s] You know what I mean?"

Here, “EB” sounds like a place to buy parts where it’s harder to get help if something is wrong. The speaker is saying you may have trouble getting a replacement compared to buying from the actual manufacturer.

Term

fuel hat assembly

"Prime example, I had that happen with a fuel company, a fuel hat assembly from a very reputable brand and I got to tell you the customer service that they provided was outstanding."

It’s a part that sits on top of your car’s fuel tank. It usually includes the fuel pump and the parts that measure fuel level, so you can replace that module instead of replacing the whole tank.

Term

pressure regulator port

"You know, essentially the whole fuel system ripped out of the car and there was a, the pressure regulator port in the fuel hat sending unit was not drilled out."

This is a connection point in the fuel system where the car controls fuel pressure. If that opening isn’t made correctly, the fuel system may not regulate pressure the way it should, which can lead to drivability issues.

Concept

recall

"There was a manufacturer in de facto. They had a recall to their sellers, but if something happened where the customer bought the seller wasn't able to contact them, it slipped through the cracks."

A recall is when a company admits a product has a problem and tries to get it fixed. The goal is to replace or correct the bad parts so they don’t cause issues.

Concept

customs

"So it's coming from out of country. So now you're shipping it in has to go through customs. I know I'm word vomiting here and it's a lot of information, but there is a chain of custody"

Customs is the border process for imported packages. If a part ships from another country, customs paperwork and checks can slow down delivery.

Concept

chain of custody

"So now you're shipping it in has to go through customs. I know I'm word vomiting here and it's a lot of information, but there is a chain of custody"

Chain of custody means keeping a clear record of who had the item and what happened to it. It helps prove the part’s history if there’s a problem or a claim.

Term

bootleg

"And it's the same thing. Even has the logos, even though it's bootleg."

“Bootleg” here means a fake product that copies the real one. It may even use similar logos, but it’s not the real, approved part.

Concept

knocking off

"…we're not teaching the next generation of car guys to respect the fact like the fact that we're outright knocking off a very, very, very popular wheel"

“Knocking off” refers to copying a popular wheel design and selling it as a substitute without authorization. In the enthusiast context, it’s often discussed alongside safety and quality concerns, because the fake part may not be engineered or tested to the same standards.

Term

rep

"It's not even like they're trying, like there were companies out there that made reps of the wheels. You know, that was the thing."

Here, “rep” means a replica—an aftermarket part that looks like a real wheel. The host is saying some replicas are trying to be replicas, while the ones they’re criticizing are just straight-up copies.

Term

rip-offs

"They're not even trying to pay homage. Oh no, it's just. They're outright rip-offs. You're stealing."

“Rip-offs” means fake copies of a wheel. The speaker’s point is that these aren’t even trying to be honest replicas—they’re just copying and selling them.

Term

billet shifters

"If you're, you see these like billet shifters that are like obvious rip-offs of a cutie or you see like, or hybrid or all these different companies, it's, it's identical."

A billet shifter is a car shifter made from a solid piece of metal that gets machined into the final shape. People like them because they look nicer and feel more solid, but some cheap copies are made to look the same.

Term

torque spack

"Like down to the, the, the number of bolts used, the torque spack, everything. So it's not like they're trying to hide it and be like, oh, this is, this is a better one."

This is about how tightly bolts are supposed to be tightened. The point is that the fake part is matching the original’s assembly details, not just the look.

Concept

direct rip-off

"No, it's still, it's a direct rip-off. Yeah. And I, and I have a problem with that."

A “direct rip-off” means a fake part that copies the real one very closely. It may look the same and be made similarly, but it’s still a copy rather than a legitimate product.

Concept

race proven

"You know, it's not a company that's race proven. You know, it's the guy that I found online that said he'll make them to the what I want."

“Race proven” means the part has been used and tested in actual racing, where failures are more likely to show up. The host is saying that experience matters when you’re trusting expensive parts.

Term

Brembo's

"And it looks, and it's similar to the, the Brembo's that I wanted. And I know we talked about this before..."

Brembo is a performance brand best known for high-end braking components like calipers and brake systems. The host compares unknown “white box” brakes to Brembo, implying Brembo has a stronger reputation and testing history.

Term

liability

"And it's not to say that it can't happen with name brands, but I feel like the risk is less. I feel like you're, you're assuming less liability when you go into it that way."

Here, “liability” is basically the risk of something going wrong. The host is saying that well-known brands tend to be safer because they’ve been tested more.

Term

injectors

"When you know that a company like Injector Dynamics has put their injectors through massive amounts of rigorous testing, you're going to trust putting those in your motor..."

Injectors are the parts that deliver fuel into the engine. If they’re not right, the engine can run poorly because it’s getting the wrong amount of fuel.

Company

Injector Dynamics

"When you know that a company like Injector Dynamics has put their injectors through massive amounts of rigorous testing, you're going to trust putting those in your motor..."

Injector Dynamics is a company that makes performance fuel injectors. The point here is that they test their parts a lot, so you can feel more confident using them.

Term

CC

"But I don't know, it doesn't have a decade of experience... that say that the right CC that just might"

“CC” is a way to describe how much fuel an injector can flow. It helps you match the injector to your engine so it can supply the right amount of fuel.

Car

Acura NSX

"...ncredible drag builds, right? You've got multiple NSXs and stuff like that. This is more of a sort of an..."

The Acura NSX is a fast sports car made by Acura. It’s designed for performance driving, and some owners modify them to make them even quicker. That’s why it can be mentioned when people talk about serious drag or performance builds.

Term

instant gratification

"Especially when you put the filter on it. That's really, I think that's part of it is we live in an age where it's one that instant gratification, it's a lot easier to buy a $300 turbo than it is to save up for a $1,600 turbo."

Instant gratification means buying something now because it feels good right away. Here, it’s about choosing the cheaper part immediately instead of waiting to afford the better one.

Concept

dopamine hit

"So you get the instant gratification, you get the dopamine hit that we get from having the cell phone out and getting the likes and looking at social media."

A “dopamine hit” is a quick feel-good reward your brain gets. The host is saying social media likes and attention can make people want to buy and post parts faster.

Concept

rip off parts

"And there were cheap rip off parts. Like I know you remember APC as you know, and their cold air intake."

“Rip off parts” means cheaper copies of popular performance car parts. They may look similar, but the materials and quality can be worse, which can affect how well they work.

Brand

APC

"And there were cheap rip off parts. Like I know you remember APC as you know, and their cold air intake."

APC is mentioned as a company that sold an aftermarket intake. The host is basically saying some of their products were copied and weren’t great quality.

Company

Advanced Auto Part

"And it wasn't good quality, but you could go right down to advanced auto part and pick one up."

Advanced Auto Parts is a common auto parts store. The host is saying you could buy these cheaper aftermarket parts there back then.

Term

air filter

"Why are you running an open air filled, open intake pipe with no air filter on the end [1274.8s] of it or whatever, you know, whatever dumb thing we were doing that week to try to be"

An air filter cleans the air before it goes into the engine. If you remove it, dust and dirt can get inside and cause extra wear over time.

Term

fake Jordan's

"But that same guy would never, ever be caught dead in fake Jordan's, right? [1319.2s] Like he'll spend however much, I don't know how much to go for now."

This is a comparison to counterfeit goods: the host is arguing that people who wouldn’t wear fake luxury sneakers still make questionable choices with car parts. The point is about perceived risk and quality control, not the sneakers themselves.

Concept

double standard

"Like he wouldn't be caught dead. [1333.0s] So it's almost like when it comes to the car stuff, there, it's almost like a double standard, [1339.0s] right?"

A double standard means people judge two things by different rules. Here, the host is saying people are skeptical about fakes in other areas, but are more willing to accept questionable stuff for cars.

Term

knockout parts

"There's certainly a divide there, but I'm just wondering now why it seems like it's so much more acceptable for people to be using knockout parts or, you know, completely fake parts as compared to, you know, years ago."

Knockoff parts are fake versions of real car parts. They might look right, but they can be made with cheaper materials and may not work as safely or reliably as the genuine ones.

Term

dyno

"Like the vehicles run, they make power, they get in the dyno or maybe they go to the track or whatever and it does the trick."

A dyno is a testing machine for cars. It measures how much power the engine is making so people can compare results before and after modifications.

Concept

YouTube builds

"Because most of the YouTube builds, they're usually there, you know, they're kind of a flash right there, there for a little bit, get the content and sort of move on to the next build."

A “YouTube build” is a car project done mainly for making videos. The concern is that some problems only appear later, after the creator moves on.

Concept

Longevity

"Long term, a little bit different, right? Because most of the YouTube builds, they're usually there, you know, they're kind of a flash right there, there for a little bit, get the content and sort of move on to the next build."

Longevity here means “will it keep working for a long time?” The point is that some builds look great at first, but later they fail or stop running—especially if the car is driven every day.

Concept

daily driver

"And then also if it's a daily driver too. It's always funny when you see like one of the cars that you know was a project car in a YouTube video and you're watching it for a long time, they built it, everything was great."

A daily driver is the car you use most days. If a part can’t handle normal everyday driving, it’s a problem even if it looks good in a quick video.

Term

ECU

"Are you okay with running it after a no name ECU? Are you okay with running no name fuel components?"

An ECU is the car’s main computer for the engine. It helps decide things like how much fuel to use and when to spark.

Term

fuel components

"Are you okay with running it after a no name ECU? Are you okay with running no name fuel components?"

Fuel components are parts that help deliver gas to the engine. If they’re low-quality or counterfeit, they can cause leaks or poor fuel delivery.

Term

hoses

"Do you trust hoses that come off of eBay? Like that's more of like the thing."

Hoses move important fluids or pressure around the engine. If the hoses aren’t good quality, they can crack or leak and cause problems.
