GSC Power-Division Super Alloy Exhaust Valves for Select 1990-2006 Mitsubishi/Eagle (4G63T Evo1-9) - 31.5mm (+1mm), Set of 8
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 Eclipse, Lancer Evolution, Galant VR-4, Eagle Talon, and Plymouth Laser (4G63T).
GSC Power-Division Super Alloy exhaust valves are engineered to withstand the extreme heat and cylinder pressures of high-output turbocharged 4G63T engines. These valves feature a 31.5mm head diameter—a +1mm oversize compared to factory specs—allowing for significantly improved exhaust flow and scavenging. Constructed from high-strength Super Alloy and finished with a chrome polish for reduced stem-to-guide friction, these valves are an essential upgrade for DSM and Evolution builds pushed beyond stock limits.
