Supertech Mini / Dodge Neon / Mitsubishi 420A 6mm Viton Integral Valve Stem Seal - Single

Supertech is known for making well-built internal engine components. This single valve stem seal is made from Viton, a material that holds up well to heat and oil, making it a solid choice for your Mini, Dodge Neon, or Mitsubishi 420A engine.

This seal features an integral design, meaning the spring retainer is built right into the seal itself. It's designed for a 6mm valve stem, which is common in many performance and everyday applications. When you're rebuilding an engine or just replacing worn-out seals, using a material like Viton helps prevent oil from leaking down the valve guides and into the combustion chamber, which can cause blue smoke and increased oil consumption.
