Supertech SR20DE/SR20DET/RB26 6mm Intake Valve Stem Seal - Set of 12

This set includes 12 Supertech 6mm intake valve stem seals, designed for SR20DE, SR20DET, and RB26 engines. These seals are crucial for preventing oil from entering the combustion chamber through the valve guides. When valve stem seals wear out, you might notice increased oil consumption, blue smoke from the exhaust, especially after idling or on startup, and fouled spark plugs. Replacing them is a key part of engine maintenance, particularly when rebuilding or refreshing an engine.

Supertech makes these seals with durable materials to withstand the heat and stress of engine operation. The 6mm stem size is specific to the intake valves on these popular Nissan engines. Proper installation ensures a tight seal, helping to maintain engine performance and reduce emissions.
