Supertech Mitsubishi 4G63/4G63T Inconel Exhaust Valves, +1mm Oversize, Set of 8
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Designed to withstand the extreme thermal loads found in high-boost Mitsubishi 4G63 and 4G63T engines, this set of 8 Supertech Inconel exhaust valves provides the high-temperature stability required for competitive motorsport and high-performance street builds. Using an Inconel 751 nickel-based alloy, these valves are engineered for superior heat resistance compared to standard stainless steel, preventing head deformation and failure under intense exhaust gas temperatures.
These +1mm oversize valves are designed to optimize flow through the exhaust ports. Please note that installing oversized valves requires professional machine work to enlarge the factory valve seats. This set is a direct performance upgrade for built cylinder heads in Mitsubishi Evo I-IX and DSM platforms.
- Material: Inconel 751 Nickel-based alloy for extreme heat resistance
- Head Diameter: +1mm oversize for increased flow
- Application: Mitsubishi 2.0L 4G63 / 4G63T engines
- Quantity: Complete set of 8 exhaust valves
- Manufacturer Part Number: MEVI-1009-8
