GSC Power-Division Chrome Polished Exhaust Valve Set - 31.5mm (+1mm) for Select 1990-2006 Mitsubishi/Eagle (4G63T) - 8 Pack
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1990-2006 Mitsubishi Lancer Evolution, Eclipse, Galant VR-4, Eagle Talon, and Plymouth Laser (4G63T).
GSC Power-Division chrome polished exhaust valves are engineered to handle the increased thermal loads and flow requirements of high-performance 4G63T builds. These valves feature a +1mm oversized head diameter (31.5mm), designed to improve exhaust scavenging and overall volumetric efficiency when used with a performance valve job. The chrome polished finish reduces friction and prevents carbon buildup on the valve face and stem, ensuring consistent seating and durability in both DSM and Evolution cylinder heads.
- Head Diameter: 31.5mm (+1mm Oversize)
- Material: Chrome Polished
- Quantity: Set of 8 Exhaust Valves
- Application: Mitsubishi 4G63T (Evo 1-9 and 1G/2G DSM)
- Manufacturer Part Number: 2003-8
This set replaces worn factory exhaust valves and is ideal for forced induction applications where reliability at high RPM and elevated boost levels is critical.
