Cylinder head for Nissan G9T

The cylinder head, part number 1104100Q0D, serves as the upper closure for the engine block in Nissan G9T and ZD3 engines. It seals the cylinders to create the combustion chambers where the air-fuel mixture is ignited. This component integrates the intake and exhaust ports, valve seats, valve guides, and the mounting points for fuel injectors and spark plugs or glow plugs. It also contains passages for the engine coolant to circulate, which allows the head to dissipate heat generated during the combustion process.

This component is engineered to maintain the necessary compression levels within the engine cylinders. Proper sealing is required to ensure consistent power output, fuel efficiency, and emission control. The cylinder head is compatible with Nissan G9T and ZD3 engine configurations. It is designed to house the valvetrain components and manage the flow of gases in and out of the engine, ensuring the mechanical timing and pressure requirements are met during operation.
