Supertech Ford Coyote 5.0L 6mm Stem Viton Intake/Exhaust Valve Stem Seal - Single

If you're rebuilding the top end of your Ford Coyote 5.0L engine, these valve stem seals from Supertech are a solid choice. They're designed to fit the 6mm valve stems found on both intake and exhaust valves, helping to keep oil from entering the combustion chamber. Proper sealing here is crucial for maintaining compression and preventing excessive oil consumption.

These 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-temperature environment. Viton seals tend to last longer and hold up better under demanding conditions compared to standard rubber seals. This particular part number is for a single seal, so be sure to order enough to replace all of them on your engine.
