Supertech Mitsubishi 6.6mm Intake Valve Stem Seal Viton (STD Size) - Set of 8

Supertech is known for making solid internal engine components. For your Mitsubishi engine rebuild, these intake valve stem seals are a critical part of getting the top end sealed up right. They keep oil from getting past the valve guide and into the combustion chamber, which helps prevent smoking and oil consumption.

This set includes eight seals, made with Viton material for good resistance to heat and oil. The 6.6mm stem size means they're intended for specific Mitsubishi intake valves, and they're the standard size. Getting these installed correctly is key to a healthy engine after a rebuild or when you're addressing oil burning issues.
