Ferrea Mitsubishi 4B11T 36mm 5.47mm 113.25mm +1mm Comp Plus Int Valve - Single (Drop Ship Only)

This is a single Ferrea Comp Plus intake valve designed for Mitsubishi 4B11T engines. It measures 36mm in diameter with a 5.47mm stem and a length of 113.25mm, featuring a +1mm oversized head for improved airflow. These valves are a popular choice when rebuilding or upgrading the cylinder head on a 4B11T, helping to increase the engine's breathing capacity.

Ferrea valves are known for their well-built construction. The Comp Plus line uses specific alloys and heat-treating processes to ensure durability under demanding conditions, making them suitable for performance applications where stock valves might not hold up. The +1mm oversized head is a common modification to increase the valve's surface area, which can lead to better cylinder filling and potentially more power. Installation involves replacing the stock intake valves during a cylinder head overhaul.
