Ferrea Competition Plus Intake Valve [STOCK SIZE] R34 NEO RB25DET


Ferrea Racing Component’s Competition Plus Valves have built a reputation as the industry’s most reliable racing valve. We, at Ferrea, are dedicated to providing the absolute best product on the market.

Our extensive R & D programs provide technological enhancements that are implemented in each of our competition plus valves. They are engineered for high rpm’s, high horsepower racing engines, and are chosen by many top Drag, Oval Track, Road Racing and Sprint Car teams.

To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to thematerial structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip. Our engineering staff at Ferrea spends countless hours conducting flow bench tests to achieve an optimum balance of flow, velocity and efficiency in the design of these valves. As a result, these valves incorporate smoother radiuses and unique undercuts. These exclusive features are what make the Ferrea Competition Plus Valves unequalled in performance and reliability!

The evolution in volumetric efficiency of today’s competition engines has increased the average engine EGT. These higher Exhaust Gas Temperatures decrease the longevity of the valves as well as creating higher levels of metallurgical fatigue. These increased stress loads create an environment in the engine conducive to valve failure.

The exhaust valves in the Competition Plus series are manufactured from Ultra High Strength, High Temp Nickel Stainless Steel Alloys. Ferrea first used this material with great success during the development of a very high stress, high temp endurance racing program.

Listed below are some qualities of the Competition Plus Exhaust Valve material:
• Tensile strength increased by 20% at high temperature
• Fatigue resistance increased by 20%
• Valve seat life increased by 25%
