Supertech BMW 6mm Stem Viton Exhaust Valve Stem Seal - Set of 12

This set includes 12 Supertech Viton exhaust valve stem seals, each designed for a 6mm valve stem. These seals are crucial for keeping oil out of your engine's exhaust ports, which helps prevent blue smoke from the tailpipe and can improve engine performance by maintaining proper compression.

Made with Viton material, these seals offer good resistance to heat and oil, making them a solid choice for exhaust valve applications where temperatures can get high. They are designed to fit right onto your BMW's 6mm valve stems, helping to ensure a proper seal and prevent oil consumption. If you're rebuilding your engine or addressing oil burning issues, replacing these seals is a common and effective step.
