Supertech Subaru EJ25/Toyota 3SGTE/4AGE 16V / 7MGTE 6mm Polyacrylic Int Valve Stem Seal - Set of 12

If you're rebuilding the top end of your Subaru EJ25, or Toyota 3SGTE, 4AGE 16V, or 7MGTE engine, replacing the valve stem seals is a critical step. These intake valve stem seals from Supertech are made from polyacrylic, a material known for its good resistance to heat and wear, making them a solid choice for these performance-oriented engines. They are designed to fit 6mm valve stems, which is common on many performance applications.

This set includes 12 seals, enough for a typical 4-cylinder engine's intake valves. Proper installation of these seals helps prevent oil from leaking down the valve guides into the combustion chamber, which can cause blue smoke on startup and increased oil consumption. Using new seals during a rebuild ensures a cleaner burn and helps maintain engine performance.
