Supertech Mitsubishi 4B11 EVO X Inconel Exhaust Valve - +1mm Oversize - Single (Drop Ship Only)

If you're rebuilding the top end of your Mitsubishi 4B11 EVO X engine, especially if you're pushing more power or dealing with high exhaust gas temperatures, you'll want to consider these Supertech Inconel exhaust valves. They are designed to handle the extreme heat and stress that stock valves can struggle with, helping to ensure reliable performance under demanding conditions.

These valves are made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to high temperatures and corrosion. This makes them a solid choice for performance builds or engines that see a lot of track time. This particular valve is 1mm oversize, which can be beneficial when reconditioning valve seats or when a slight increase in flow is desired. They are sold individually, so you can order exactly what you need for your rebuild.
