BLOX Racing Honda 5.5mm Valve Stem Seals Blue FKM - Set of 16 (Fits Both Intake & Exhaust)

This set includes sixteen blue FKM valve stem seals from BLOX Racing, designed to fit both intake and exhaust valves on 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 on startup, increased oil consumption, or fouled spark plugs.

These seals are made from FKM (Fluoroelastomer), a material known for its resistance to heat and oil, which is important for the demanding environment around the combustion chamber. The 5.5mm size is specific to certain Honda engine applications, ensuring a proper fit when installed. Replacing worn valve stem seals is a common part of engine rebuilding or repair to restore proper oil control and engine performance.
