1. Enhance your 6.0L Powerstroke Diesel’s performance with our premium 21-4N Forged Stainless Intake Valves, designed to deliver a remarkable 10+ CFM increase in airflow over stock valves.

2. Featuring a valve stem that is 21% smoother than traditional chrome-plated options, these valves significantly reduce friction between the valve and valve guide, resulting in less wear and increased power output.

3. Crafted for durability, our valves are stronger and more corrosion-resistant than chrome-plated alternatives, ensuring longevity even in demanding conditions, including the use of exotic fuels. . The five-step liquid nitration process enhances ductility and minimizes the risk of breakage, even upon piston contact, while also being environmentally friendly compared to conventional chroming methods.
