Ferrea Mitsubishi 4G63/4G63T 31.5mm 6.55mm 20 Deg Flo +1mm Comp Plus Exh Valve - Set of 8

These Ferrea Comp Plus exhaust valves are built with a specific material choice in mind: high-strength stainless steel that can handle the heat and stress inside your Mitsubishi 4G63 or 4G63T engine. They measure 31.5mm in diameter with a 6.55mm stem and feature a 20-degree face angle, which is a design choice that helps improve airflow compared to a standard valve seat.

This set includes eight valves, each with a +1mm oversized head. This slight increase in diameter is a common modification for the 4G63 engine to help it breathe better, especially when you're looking to get more performance out of your build. The Comp Plus line from Ferrea is known for its well-built construction, designed to be a solid option for engines that see regular use and demand reliable performance.

When you're rebuilding the top end of your 4G63 or 4G63T, using valves like these from Ferrea ensures you're putting in components that are made to last and perform. They are a direct replacement for the stock exhaust valves, making installation straightforward if you're already doing a valve job or cylinder head work.
