Ferrea Acura/Honda 5.5mm Viton Hi-Temp Exhaust Valve Stem Seal - Set of 8

If you're rebuilding the top end of your Acura or Honda engine, you'll need a solid set of valve stem seals. This set from Ferrea is designed for exhaust valves and uses Viton material, which can handle the higher temperatures found in exhaust ports. These seals help prevent oil from leaking down the valve guide and into the combustion chamber, which can cause blue smoke on startup and increased oil consumption.

Ferrea is known for making well-built engine components, and these valve stem seals are no exception. The 5.5mm size is specific to many Acura and Honda applications, ensuring a proper fit on the valve stem. Installing new seals is a crucial step when you've got the cylinder head off, helping to restore proper engine function and reduce emissions.
