Supertech Honda 5.5mm Polyacrylic Intake Valve Stem Seal - Set of 8

This is a set of eight Supertech 5.5mm polyacrylic intake valve stem seals for Honda engines. Valve stem seals are crucial for preventing oil from entering the combustion chamber through the valve guides. When these seals wear out, you might notice blue smoke from your exhaust, especially after the engine has been idling or when you first start it up. Replacing them is a common part of engine rebuilding or when addressing oil consumption issues.

These seals are made from polyacrylic, a material known for its good resistance to heat and wear, making them a solid choice for intake applications where temperatures can get quite high. The 5.5mm size is specific to certain Honda engine valve stems, ensuring a snug fit to do their job effectively. Installing these seals is typically done during a cylinder head removal or rebuild process, and they fit right onto the valve guides.
