Key Information

The injector sleeve is a precision-engineered component that acts as a sealed housing for the fuel injector within the cylinder head. It creates a critical barrier between the high-pressure fuel system and the engine's combustion chamber and cooling galleries.

This sleeve ensures the fuel injector is perfectly aligned and secured. It is designed to withstand the extreme pressures and temperatures of the combustion chamber, preventing combustion gases from escaping into the fuel system or coolant from entering the combustion area.
