Cylinder head for Nissan ZD30

The cylinder head 1104100Q0REX mounts to the top of the engine block, creating a seal for the cylinders and forming the combustion chamber where air and fuel ignite. This component houses the intake and exhaust valve mechanisms, including their seats and guides. Internal passages within the casting allow for the circulation of engine coolant to manage thermal loads during operation.

This part is compatible with the Nissan ZD30 engine. It serves as the primary interface for gas exchange, controlling the flow of intake air and exhaust gases through the valve assembly. Proper installation ensures the integrity of the combustion chamber, which is necessary for maintaining engine compression and preventing fluid leaks between the cooling system and the cylinders.
