A single polished super-alloy exhaust valve for Mitsubishi 4G63T engines (Evo I–IX) with a 31.5mm +1mm head. This oversize option supports rebuilds and head machining where larger exhaust valve diameter is required for flow or fitment. Sold individually for selective replacement, the super-alloy construction provides a more robust choice for high-heat exhaust conditions encountered in modified or high-output engines.
