ITBs

Too Afraid to Ask

ITBs are individual throttle bodies, meaning each cylinder gets its own throttle. They can make the engine feel sharper, but they’re harder to tune and can be more annoying day-to-day. The host is choosing to avoid that complexity.

Technical Definition

ITBs stands for individual throttle bodies—separate throttle plates for each cylinder. They can improve throttle response and airflow, but they’re often more complex to tune and maintain (fueling, synchronization, idle quality). The speaker says ITBs are too problematic for their taste, implying they prefer simpler, more reliable gains.
