Supertech Subaru BRZ / Toyota FRS Viton Valve Stem Seal - Single

If you're rebuilding the top end of your Subaru BRZ or Toyota FRS, replacing the valve stem seals is a critical step. These Supertech Viton valve stem seals are designed to keep oil from leaking past the valve guides and into the combustion chamber. Worn seals can lead to increased oil consumption, fouled spark plugs, and poor emissions.

Made from Viton, a high-performance fluoroelastomer, these seals offer excellent resistance to heat and oil. This material is known for its durability and ability to maintain its sealing properties under demanding engine conditions. Each seal is a single unit, allowing you to replace only the ones you need, which is common when you're working on a specific cylinder head or performing a partial rebuild.
