Ferrea Mitsubishi 4B11T 5.5mm Viton Intake Valve Stem Seal - Set of 8

These 5.5mm intake valve stem seals from Ferrea are made from Viton, a material known for its excellent resistance to heat and oil. When you're rebuilding the top end of your Mitsubishi 4B11T engine, replacing these seals is a critical step to prevent oil from leaking past the valve guides and into the combustion chamber. Fresh seals help maintain proper compression and keep your exhaust cleaner.

Viton is a smart choice for valve seals because it holds up well under the high temperatures found in the engine's cylinder head. This particular set includes eight seals, which is exactly what you'll need for a complete intake valve job on your 4B11T. Installing new seals is a straightforward part of a valve job, ensuring that your engine runs smoothly and efficiently after the work is done.
