Maintain proper combustion sealing with this Genuine Nissan Injector Lower Gasket, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30 diesel engine. This OEM copper washer is fitted at the base of the fuel injector, sealing the injector to the cylinder head and ensuring combustion pressure is contained within the cylinder for correct engine performance.

Over time, injector lower gaskets are designed as single-use components and must be replaced whenever injectors are removed or serviced. If reused, they can fail to seal correctly, leading to combustion leaks, carbon buildup in the injector bore, and potential injector seizure in the cylinder head. A failing seal may also cause poor engine performance, rough running, increased smoke, and loss of efficiency. Replacing it with a Genuine Nissan gasket ensures a proper factory seal and reliable engine operation.
