We, at Ferrea, are dedicated to providing the absolute best product on the market. Our extensive R \u0026amp; D programs provide technological gains, which are implemented in each of our competition plus valves. They are engineered for higt rpm, high horsepower racing engines, and are chose by many top NASCAR, Drag, and Oval \u0026amp; Sprint Car-racing teams.To manufacture the valves we use special aerospace quality alloys, including EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminated any damage to the material 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 this valve. As a result, these valves incorporate smoother radiuses and unique undercuts. These exclusive features are what make the Ferrea Competition Plus Valves unequaled in performance and reliability! \u003cbr\u003e\u003cbr\u003e Ferrea is once again setting the pace with its Competition Plus PQ Series Exhaust Valves, the next generation of exhaust valve technology.Due to the evolution in today's competition engine applications, temperatures are increasing and as a result, longevity is decreasing.

This air intake system was designed, tuned and dyno-tested to fit specific Subaru WRX STI models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable textured red powder coated finish. This air intake system was developd to accommodate the engine's factory emissions control devices including the mass air flow sensor. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards while others are 50 state legal.
