Ferrea Acura/Honda 5.5mm Viton Hi-Temp Exhaust Valve Stem Seal - Single (Drop Ship Only)

When you're rebuilding the top end of your Acura or Honda engine, making sure the valve seals are in good shape is crucial. These Ferrea 5.5mm Viton Hi-Temp Exhaust Valve Stem Seals are designed to keep oil from leaking past the valve guides and into your combustion chambers. A worn-out seal can cause blue smoke on startup, increased oil consumption, and fouled spark plugs, so replacing them is a key part of any engine overhaul or repair.

Ferrea uses Viton material for these seals, which can handle the high temperatures found around exhaust valves. The 5.5mm size is specific for many Acura and Honda applications, ensuring a snug fit on the valve stem. Installing these seals properly is important; they should be seated firmly to create a good seal without damaging the valve stem or the seal itself. This is a single seal, so you'll need to order one for each exhaust valve you are servicing.
