Supertech Mitsubishi 4G63/4G63T Black Nitrided Exhaust Valve - Set of 8

Supertech is known for making well-built valvetrain components, and this set of eight black nitrided exhaust valves for the Mitsubishi 4G63 and 4G63T engines is a prime example. If you're rebuilding or upgrading the top end of your 4G63-powered vehicle, these valves are designed to handle the demands of performance applications.

The black nitriding process hardens the surface of the valve, making it more resistant to wear and fatigue. This is especially important for exhaust valves, which operate under high temperatures and pressures. These valves are made to fit the specific dimensions required for the 4G63 cylinder head, ensuring a proper seal and efficient operation. Having a full set of eight means you can replace all your exhaust valves at once for a complete valvetrain refresh.
