Ferrea Mitsubishi 4G63/4G63T 35mm 6.57mm 20 Deg S-Flo +1mm 6000 Series Intake Valve - Set of 8

The Ferrea Mitsubishi 4G63/4G63T 35mm 6.57mm 20 Degree S-Flo +1mm Intake Valve set is a high-performance engine component designed to enhance airflow and combustion efficiency in Mitsubishi 4G63 and 4G63T engines. Crafted from durable 6000 Series aluminum, these intake valves feature a 35mm diameter, 6.57mm stem thickness, and a 20-degree S-Flo profile, optimized for improved airflow and fuel atomization. The +1mm size indicates a slight increase in valve length, supporting higher lift and better volumetric efficiency. Built for strength and reliability, these valves are ideal for performance upgrades, racing, or high-performance street applications, providing increased horsepower and torque through precise engineering and quality materials.

Designed to fit Mitsubishi 4G63 and 4G63T engines, typically found in models from the late 1980s through the 2000s, this set is a direct replacement for stock intake valves. Suitable for use in turbocharged or naturally aspirated setups, these valves are intended for performance enthusiasts seeking to maximize engine output. Installation involves replacing existing intake valves with these upgraded components, making them suitable for rebuilds or engine builds focused on racing or high-performance driving. The set includes eight valves, ensuring complete cylinder head compatibility, and offers a reliable upgrade for those aiming to improve airflow and overall engine efficiency in street or track applications.
