This is a Genuine Nissan gasket that seals the turbocharger to the exhaust manifold. It is specifically designed for the 4-bolt turbo flange found on Spanish-built Nissan Navara D40 and Pathfinder R51 models equipped with the YD25 engine, manufactured from January 2010 onwards. Located between the turbo's mounting flange and the engine's exhaust manifold, this gasket is critical for maintaining correct boost pressure and preventing dangerous exhaust leaks into the engine bay.
Over time, the original gasket perishes due to constant exposure to extreme heat and pressure cycles from the turbo and exhaust system. Signs of a faulty gasket include a noticeable loss of turbo boost, reduced engine performance, or an audible exhaust leak. This multi-layered metal shim gasket is the factory-correct replacement to restore a perfect, long-lasting seal and bring your vehicle's performance back to where it should be.
Replacing this gasket is a moderate workshop job that requires disassembly of the turbocharger from the exhaust manifold. Access can be tight, and fasteners may be seized due to heat cycles. For a complete and reliable repair, it is highly recommended to replace the turbo mounting studs and nuts at the same time.
