GSC Power-Division Viton 6.6mm Valve Stem Seal Set for 1990-2006 Mitsubishi, Eagle & Plymouth (4G63T)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Maintain precise oil control and cylinder head integrity with the GSC Power-Division Viton 6.6mm Valve Stem Seal Set. Fits select 1990-2006 Mitsubishi Lancer Evolution, Eclipse, Galant VR-4, Eagle Talon, and Plymouth Laser models equipped with the 4G63T engine.
These seals are manufactured from high-grade Viton, a synthetic rubber known for its exceptional thermal stability and resistance to chemical degradation. In high-performance 4G63T builds where increased boost and elevated exhaust gas temperatures (EGTs) are common, Viton provides a significantly more durable solution than standard nitrile or polyacrylate seals. These seals ensure a tight fit against the valve stem to prevent oil from entering the combustion chamber through the guides, reducing smoke and carbon buildup.
- Material: High-temperature Viton synthetic rubber
- Stem Diameter: 6.6mm
- Application: 16-valve 4G63T engines
- Kit Contents: Full engine set
- Manufacturer Part Number: 1002
