Function:
•  It seals the fuel injector where it sits in the cylinder head of the engine.
•  Prevents fuel leaks and keeps air from entering around the injector.
•  Ensures the injector delivers the correct fuel spray and pressure into the combustion chamber.

Why It Matters:
•  If the sleeve/seal wears out, you can get fuel odors, leaks, or misfires.
•  A bad seal lets air escape or enter, messing up the engine’s fuel-air mixture and causing rough idle or performance loss.
•  It also prevents heat and vibration damage to the injector itself, extending its life.
