Supertech VW/Audi 8mm Viton Exhaust Valve Stem Seal - Single

This listing is for a single Supertech 8mm Viton exhaust valve stem seal. 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 on startup or deceleration, and an increase in oil consumption. Replacing them is a common part of engine rebuilding or top-end repairs to ensure proper engine health and emissions.

Made from Viton, a high-performance fluoroelastomer, these seals are built to withstand the high temperatures and harsh conditions found around exhaust valves. Viton offers excellent resistance to oil, fuel, and heat, making it a durable choice for this critical engine component. The 8mm size is specific to certain VW and Audi engine applications, ensuring a precise fit when installed correctly. While this listing is for a single seal, it's important to order the correct quantity needed for your specific engine, as most engines will require multiple seals.
