Ferrea Mitsubishi 4G63/4G63T 35mm 6.57mm 109.7mm 20 Deg S-Flo +1mm Comp Plus Intake Valve - Set of 8

Ferrea is well-known for making solid engine components, and these Comp Plus intake valves are a great example of that. If you're rebuilding the top end of your Mitsubishi 4G63 or 4G63T engine, these valves are designed to handle the demands of performance builds. They are built with high-strength materials to ensure they can withstand higher cylinder pressures and temperatures.

These valves feature a +1mm oversized head diameter, measuring 35mm, which helps increase airflow into the combustion chamber. The S-Flo design and 20-degree seat angle are also part of how they improve airflow. At 109.7mm in length, they are designed to fit within the stock valve guide spacing, making them a direct replacement for your original valves, albeit with improved performance characteristics. This set includes eight valves, enough for a full cylinder head.
