Maintain a proper fuel injector seal and stable engine performance with this Genuine Nissan Injector Upper Insulator, designed for Nissan Patrol GU Y61 models fitted with the TB45 engine. This OEM component sits between the fuel injector and the fuel rail/intake assembly, helping to correctly locate the injector while sealing against fuel leaks and vibration.

Over time, injector insulators can harden, crack, or deform due to heat and fuel exposure. A worn insulator may cause fuel seepage, poor idle quality, fuel odours, or inconsistent engine performance. Replacing these components helps ensure correct injector seating and reliable fuel system operation.

Manufactured to genuine Nissan specifications, this direct-fit insulator provides accurate fitment, durable sealing, and long-lasting performance under engine bay heat and pressure.
