Supertech Honda 5.5mm Viton Exhaust Valve Stem Seal - Single (Drop Ship Only)

If you're rebuilding the top end of your Honda 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 where the exhaust valve meets the stem. Properly sealing this area prevents oil from getting drawn into the combustion chamber, which can cause blue smoke out the tailpipe and increased oil consumption.

This is a single seal, so you'll need to order one for each exhaust valve on your engine. The 5.5mm size is specific to certain Honda applications, so make sure this is the correct size for your build. Viton seals are a solid choice for their durability and ability to withstand the high temperatures found around the exhaust valves.
