Maintain proper injector sealing and prevent fuel leaks with this Genuine Nissan Injector Gasket Washer (Lower), designed specifically for Nissan Patrol GQ and GU models fitted with the RD28 petrol/diesel engine. This OEM washer sits under the injector, forming a vital seal between the injector nozzle and cylinder head to avoid fuel seepage and ensure correct combustion performance.

Over time, injector gasket washers can harden, crack, or deform due to heat cycles, vibration, and exposure to fuel and combustion by-products. A worn or damaged washer can lead to hard starting, rough idle, misfires, fuel odor, or poor engine performance.

Manufactured to genuine Nissan specifications, this direct-fit replacement washer restores effective sealing, helps maintain proper fuel delivery, and ensures reliable engine operation in everyday driving, touring, and work conditions.
