This listing is for a single Ferrea Comp Plus intake valve designed for Mitsubishi 4G63 and 4G63T engines. You get one intake valve with a 35mm head diameter, a 6.57mm stem diameter, and an overall length of 109.7mm. It features a 20-degree seat angle and is +1mm oversized, meaning it's 1mm larger in diameter than the stock valve.

Ferrea valves are known for their robust construction, and the Comp Plus line is built to handle the demands of performance engines. This valve uses a specific material composition and heat treatment process to ensure durability and resistance to wear, especially under higher cylinder pressures and temperatures. The +1mm oversized design allows for improved airflow into the combustion chamber, which can contribute to better engine performance when paired with appropriate cylinder head work.

When rebuilding or upgrading your 4G63 or 4G63T engine, using valves that are precisely manufactured is important for proper sealing and longevity. This single valve is intended for applications where you might be replacing just one damaged valve or are performing a specific cylinder head modification. Always ensure you have the correct quantity and type of valves for your engine build.
