Maintain proper fuel injector sealing and consistent engine performance with this Genuine Nissan Injector Insulator, designed for Nissan Patrol GQ Y60 models fitted with the TB42 engine. This OEM insulator sits between the fuel injector and intake manifold, acting as both a heat barrier and a precision sealing surface to ensure correct injector operation and fuel delivery.

Over time, the original injector insulator can become brittle, cracked, or compressed due to constant heat cycling and fuel exposure. A worn insulator may lead to vacuum leaks, poor fuel atomisation, rough idle, increased fuel consumption, or hard starting issues. Replacing these components helps restore proper injector seating and ensures reliable engine performance.

Manufactured to genuine Nissan specifications, this direct-fit replacement delivers precise fitment, durable heat-resistant construction, and long-lasting sealing performance for daily driving, towing, touring, and off-road conditions.
