Ferrea Subaru EJ20 6mm Viton Hi-Temp Intake Valve Stem Seal - Set of 8

These 6mm intake valve stem seals from Ferrea are made from Viton, a high-temperature resistant material. This is important because the intake valves are located in a hot part of the engine, and these seals need to hold up under those conditions. They are designed to keep oil from getting past the valve guide and into the combustion chamber, which helps prevent blue smoke from the exhaust and can improve engine performance.

When you're rebuilding the top end of a Subaru EJ20 engine, replacing the valve stem seals is a critical step. These Ferrea seals are a solid option for the job. Viton is known for its durability and resistance to heat and chemicals, making it a good choice for this application. Having a set of eight means you'll have enough to replace all the intake seals on your engine.
