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

This is a single Ferrea 5.5mm Viton intake valve stem seal, part number VS1003-1. It's designed to fit many Acura and Honda engines, helping to keep 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 sitting for a bit or when you first start it up.

Ferrea uses Viton material for these seals, which is known for its excellent resistance to heat and oil. This means the seal can handle the demanding environment inside your engine and last a long time. Because it's a direct fit for many popular Acura and Honda applications, installation should be straightforward if you're already working on the cylinder head or valve train.

Since these seals are sold individually, make sure to order the correct quantity for all your intake valves. It's a good idea to replace them whenever you have the cylinder head off for other work, like replacing valve springs or performing a valve job.
