VALVE - EXHAUST (Nissan NI9005258-26H)

A worn exhaust valve can allow combustion gases to escape past the seat, reducing cylinder compression and causing rough idle. This aftermarket replacement part references Nissan as the OE maker and carries the cross-reference number NI9005258-26H. The valve controls the release of spent gases from the combustion chamber during the exhaust stroke. Over time, carbon buildup or heat damage may cause the valve to stick or fail to seal properly. A failed exhaust valve often leads to misfire, backfiring, or a noticeable loss of power. Verify the serial number or application, then call (562) 693-7748. Call (562) 693-7748 after checking the serial number or application.
