Supertech Mitsubishi 4G63/4G63T Inconel Exhaust Valve - +1mm Oversize - Single (Drop Ship Only)

Supertech is known for making well-built internal engine components, and this Inconel exhaust valve is a prime example. If you're rebuilding the top end of your Mitsubishi 4G63 or 4G63T engine, this valve is designed to handle the heat and stress of performance applications.

This particular valve is made from Inconel, a high-nickel alloy that's exceptionally resistant to high temperatures and corrosion. That makes it a strong choice for exhaust valves, which are exposed to the hottest gases leaving the combustion chamber. It's also a +1mm oversize valve, meaning it's slightly larger than stock. This can help improve sealing and potentially increase flow when used in a performance build, especially if the valve seat has been opened up to match.

This is a single valve, so be sure to order the correct quantity for your engine build. It's a direct replacement for your stock valve, but it's always a good idea to check manufacturer specifications for your specific application.
