Maintain proper fuel injector sealing and engine performance with this Genuine Nissan Injector Insulator designed to suit Nissan Patrol GU models fitted with the TB45 petrol engine. This OEM injector insulator helps create a secure seal between the fuel injector and intake manifold, preventing air leaks and ensuring consistent fuel delivery.

Over time, injector insulators can harden, crack, or deteriorate due to engine heat and age, leading to vacuum leaks, rough idle, poor fuel economy, and inconsistent engine performance. Replacing worn insulators during injector servicing helps restore smooth engine operation and reliability.
