Supertech Mitsubishi 4G63/4G63T Black Nitrided Intake Valves, +1mm Oversize (Set of 8) - MIVN-1009-8
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
This set of eight Supertech black nitrided intake valves is engineered for the Mitsubishi 4G63 and 4G63T engines. Designed for high-performance builds requiring professional headwork, these +1mm oversize valves provide the increased surface area necessary to maximize airflow in ported cylinder heads.
Supertech utilizes a specialized black nitriding process that hardens the valve surface and reduces friction against the valve guide. This treatment improves thermal stability and wear resistance, making these valves ideal for high-boost and high-RPM applications where standard components may fail. The precision-machined stems ensure consistent tolerances for reliable valvetrain geometry.
- Fits Mitsubishi 4G63 and 4G63T engines (Lancer Evolution and DSM models)
- Valve Type: Intake
- Sizing: +1mm Oversize (requires machining)
- Finish: Black Nitrided for superior hardness and low friction
- Quantity: Set of 8
- Manufacturer Part Number: MIVN-1009-8
Note: Oversize valves require a professional multi-angle valve job and cylinder head machining for proper fitment and sealing.
