Ferrea Competition Plus Exhaust Valves STD (30.00mm) K20A/2/3/Z1

Ferrea Racing Component’s Competition Plus Valves have built a reputation as the industry’s most reliable racing valve. 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.

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.
