Supertech Honda 5.5mm Polyacrylic Intake Valve Stem Seal - Single (Drop Ship Only)

Supertech is known for making solid valvetrain components, and these 5.5mm polyacrylic intake valve stem seals are a good example of their focus on engine parts. If you're rebuilding the top end of your Honda engine, these seals are crucial for keeping oil from getting into your combustion chambers. They fit right onto the 5.5mm valve stems, which is common on many Honda applications.

These seals are made from polyacrylic, a material chosen for its resistance to heat and oil, which helps them last longer in the demanding environment of the cylinder head. Replacing old, hardened valve seals is a common step when you're addressing oil consumption or blue smoke on startup. It's a small part that makes a big difference in how your engine runs and how clean its emissions are.
