Ferrea Nissan NEO 29.65mm 5.96mm 97.95mm 22 Deg Flo Stock Competition Plus Exhaust Valve - Set of 12

Ferrea Racing Component’s Competition Plus Valves are engineered for high RPMs and high horsepower racing engines. These valves are manufactured from special aerospace quality alloys, including EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow, and the valves are then heat-treated and stress-relieved over a 48-hour period to ensure molecular integrity. They feature avionics-quality hard chrome and a specially applied hard tip. The design focuses on an optimum balance of flow, velocity, and efficiency with smoother radiuses and unique undercuts. The exhaust valves in the Competition Plus series are made from Ultra High Strength, High Temp Nickel Stainless Steel Alloys, a material first used with success in a high-stress, high-temperature endurance racing program. This material increases tensile strength by 20% at high temperatures, fatigue resistance by 20%, and valve seat life by 25%.
