About this part

Product Details

This listing is for a single Ferrea exhaust valve designed for the Mitsubishi 4B11T engine. You get one exhaust valve with a 30mm head diameter, a 5.46mm stem, and a length of 105.90mm. This particular valve is a +1mm oversized option, meaning it's 1 millimeter larger in diameter than the stock valve, which can be beneficial for rebuilding or performance applications where improved flow is desired. It features a single groove design and is constructed from a super alloy material, chosen for its strength and resistance to high temperatures found in exhaust ports.

Ferrea uses specialized super alloy materials for their exhaust valves, which are well-suited to handle the extreme heat and stress of the exhaust side of an engine. This material choice helps ensure longevity and consistent performance, especially in engines that are pushed harder or see frequent high-RPM operation. The +1mm sizing is a common modification when rebuilding cylinder heads to restore performance or achieve a slight increase in airflow over the intake side.
