Too Afraid to Ask

The cylinder head is the top part of an engine that holds valves and spark plugs. It helps keep the air‑fuel mixture inside the cylinders so the engine can run.

Technical Definition

Cylinder heads are the components that sit on top of an engine’s cylinders and contain valves, spark plugs, and passages for coolant and oil. They play a critical role in sealing combustion chambers and directing airflow.
