Supertech Subaru EJ25 / Toyota 3SGTE/4AGE 8mm Polyacrylic Int Valve Stem Seal - Single (D/S Only)

This listing is for a single Supertech polyacrylic valve stem seal designed for the intake valves of Subaru EJ25 engines and Toyota 3SGTE and 4AGE 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 blue smoke from your exhaust, especially after the engine has been sitting or when you first start it up.

Made from polyacrylic, these seals offer good resistance to heat and oil, which is important for their longevity in an engine environment. The 8mm size is specific to the valve stems on the listed Subaru and Toyota engines. If you're rebuilding the top end of your engine or replacing worn valve seals, these single seals allow you to purchase exactly what you need for the intake side.
