Supertech Mitsubishi 4G63/4G63T Inconel Exhaust Valve - +2mm Oversize - Single (Drop Ship Only)

This is a single Supertech Inconel exhaust valve designed for Mitsubishi 4G63 and 4G63T engines. It's built to a +2mm oversize specification, meaning it's slightly larger than the stock valve. This can be beneficial for improving flow and performance, especially in modified engines where increased airflow is desired.

Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures. This makes it a solid choice for exhaust valves, which are subjected to the intense heat and pressure of combustion. The +2mm oversize dimension is a specific modification that can help maximize the valve's sealing surface and potentially increase the volume of the combustion chamber slightly, contributing to improved performance when paired with other engine upgrades.
