6000 Series Stock-Size Intake Valve

The Ferrea 6000 Series Stock Size Intake Valves are engineered for exceptional reliability in demanding racing environments, even with high spring pressures and roller cams, all at a budget-friendly price point. These valves offer superior fatigue resistance and tensile strength compared to many competitor offerings. Manufactured using Ferrea's exclusive two-step slow forging process with EV8 stainless steel for both intake and exhaust valves, these components undergo a special heat-treatment and stress-relieving process. They are further enhanced with hard chrome stems and friction-welded hard tips, finished with a swirl-polished head to optimize airflow and power delivery for modern racing engines. Key specifications include a 35mm head diameter, 5.47mm stem diameter, and an overall length of 113.25mm. The reference for these valves is a 15-degree Super Flo design, maintaining stock size. These valves are sold individually, and customers should use the quantity selector to order the required number for their build. These intake valves are specifically designed for the 2008-2015 Mitsubishi Evo X. They come with the manufacturer's standard warranty.
