Supertech Mitsubishi Evolution X 4B11 Integral Valve Stem Seals - Set of 16 (VSI-M5.5V-16)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits Mitsubishi Lancer Evolution X models equipped with the 4B11 engine.
Maintain precise oil control in your cylinder head with this set of 16 Supertech integral valve stem seals. These seals are engineered to withstand the high thermal loads and increased cylinder pressures common in turbocharged 4B11 applications. By providing a consistent seal against the valve stem, they prevent oil from migrating down the guide into the combustion chamber—eliminating the blue smoke and carbon buildup associated with worn factory seals.
Designed for both street and track use, these Supertech seals are manufactured to strict tolerances for long-term durability. This complete set provides all 16 seals required for a full intake and exhaust service on the 4B11 engine.
- Manufacturer Part Number: VSI-M5.5V-16
- Fitment: Mitsubishi Evolution X (4B11 Engine)
