Supertech VW/Audi / BMW 6mm Viton Exhaust Valve Stem Seal - Set of 8

If you're rebuilding the top end of your VW, Audi, or BMW engine, replacing the valve stem seals is a critical step. These Supertech seals are made from Viton, a material known for its excellent resistance to heat and oil, which is exactly what you need in this high-stress area. Properly sealing the valve guides stops oil from getting past the valve stem and into your combustion chamber, preventing blue smoke on startup and reducing oil consumption.

This set includes eight 6mm seals, designed to fit specific exhaust valve stems on many popular VW, Audi, and BMW models. Viton is a durable material that holds up well under the high temperatures found around the exhaust valves. Making sure these are seated correctly during installation will ensure they do their job effectively for a long time.
