Supertech VW/Audi / BMW 6mm Polyacrylic Intake Valve Stem Seal - Single (Drop Ship Only)

When you're rebuilding the top end of your VW, Audi, or BMW engine, replacing the valve stem seals is a critical step. These seals keep oil from getting into the combustion chamber through the valve guides, which helps prevent smoking and oil consumption. This single seal is made from polyacrylic, a material known for its good resistance to heat and wear, making it a solid choice for intake valves.

This Supertech seal is designed for 6mm valve stems, a common size in many VW, Audi, and BMW engines. Installing new seals ensures a proper seal around the valve stem, which is essential for maintaining good compression and preventing oil from fouling your spark plugs. It's a small part, but it makes a big difference in how your engine runs and how clean it burns.
