Restore proper fuel injector sealing and engine performance with this Genuine Nissan Lower Injector Insulator, designed to suit Nissan Patrol GU Y61 models fitted with the TB45 4.5L petrol engine. This OEM insulator is fitted at the lower section of the fuel injector and helps create a secure seal between the injector and the intake manifold, ensuring correct fuel delivery and preventing air leaks.

Over time, injector insulators can become hardened, brittle, compressed, or damaged due to heat exposure, fuel system servicing, and general engine wear. A worn injector insulator can contribute to vacuum leaks, rough idle, poor fuel economy, inconsistent engine performance, and unmetered air entering the intake system.

Manufactured to genuine Nissan specifications, this replacement insulator provides the correct fit, sealing properties, and durability required to maintain factory fuel system performance. It is recommended whenever injectors are removed for servicing, replacement, or engine repairs.
