Cylinder head for Audi 3D

The cylinder head, part number 908153K, mounts to the top of the engine block to seal the cylinders and create the combustion chambers. This component integrates the intake and exhaust ports, valve seats, and the necessary openings for fuel injectors or spark plugs depending on the specific engine configuration.

This part is compatible with Audi 3D and Audi 3D LEVAS/WITH engine models. It maintains the required seal for the engine block to ensure proper compression during the combustion cycle.

A cylinder head acts as the cover for the engine cylinders, housing the valve train and managing the flow of air and fuel into the combustion chamber while directing exhaust gases out. It must maintain a precise seal against the engine block to prevent the loss of compression and the mixing of fluids such as oil and engine coolant.
