Supertech Subaru EJ25 / Toyota 3SGTE/4AGE 6mm Viton Exhaust Valve Stem Seal - Single (D/S Only)

This is a single Supertech exhaust valve stem seal made from Viton, designed for 6mm valve stems. It's specifically suited for Subaru EJ25 engines and Toyota 3SGTE and 4AGE engines, often used when rebuilding or refreshing the cylinder head.

Viton is a high-performance synthetic rubber known for its excellent resistance to heat and oil, which are common in the exhaust side of an engine. This durability helps prevent oil from leaking down the valve guide and into the combustion chamber, which can cause blue smoke on startup and increased oil consumption.

This seal is sold individually, so you'll need to order the correct quantity for all your exhaust valves.
