Stillen offers a wide range of performance parts, including the Trupower air intake scoops for a variety of vehicle makes and models. The factory air intake system on various Chevrolet Silverado/GMC Sierra vehicles is a very unique and creative design. There is no natural path for the air to flow through. The air must travel up the face of the radiator in order to make its way into the air intake opening. Keep in mind the radiators operational temperature is 180-220 degrees—significantly higher than ambient. To solve the issues with this otherwise, fantastic design the team at Stillen created a proper scoop—the Trupower, which lowers the base of the radiator shroud to be in line with the top bar of the vehicle's grille. This design allows for air to come directly into the intake system without being warmed by the radiator or disrupted by lattice type material in the radiator shroud, which eliminates the pre-heating and turbulence caused by the factory system. Order the model designed for your vehicle. Features and benefits: * Direct cold airflow * Reduced (intake) air temperatures * Textured finish for OEM fit and finish * Compatible with air intake or supercharger that uses factory air intake scoop * Easy installation

Stillen is proud to offer an active brake cooling option for R35 GT-R owners looking to improve track times and lower brake temperatures. These rear brake cooling kits are for use with both traditional iron rotors, as well as the Stillen carbon ceramic matrix brake kit. During the development of the Stillen GT R Targa rally car, Team StiIlen worked very closely with the engineers at AP Racing to develop the first aftermarket carbon ceramic brake kit in the world. One of the key components of that kit was brake cooling. Carbon ceramic brakes have an ideal operating temperature range where they perform at their best. They work well when cold, but their true performance shines through during repeated hard, high-temperature braking. However, there is a temperature threshold which should not be exceeded. During the development of the kit the engineers at AP Racing asked what we would be doing for brake cooling. We were open to all input from AP, and their instructions were to use external fans directing air to the rotors and calipers. They said regardless of how hot the air is coming off the engine, it's a lot cooler than the heat coming off the rotors. To test the performance of its Active Brake Cooling Kit, Stillen went to El Toro Air Force Base with temperature sensors on each rotor and caliper. They ran the tests with the active cooling on one side of the car, and not the other. They performed a series of 140-0 runs as well as laps around the test track. They also put temperature sensor stickers on each caliper that act just like temperature paint for the rotor. As the temperature of the caliper increases, it burns off parts of the sticker—so it was known how hot the caliper is running. After all of the data was collected and analyzed, engineers determined that this brake cooling kit successfully reduced rotor temperatures by over 200 degrees. The front brake cooling kit consists of a weather-resistant electric fan, mounting brackets, wiring kit and switch, and polyurethane air diversion splitter. The rear brake cooling kit consists of polyurethane air scoops which take advantage of the factory NACA ducts in the belly pan, accordion tube, polyurethane air funnel and mounting bracketry. Stillen brake cooling kits are offered as separate front and rear kits. During testing, Stillen also found that with the VDC off, the rear brake cooling isn't 100 percent necessary. Because brakes work better with a bit of heat in them, Stillen prefers to leave the brake cooling kit off of the car when Steve Millen drives because he does not utilize the VDC control system. If you are like 99 percent of GT-R owners, you more than likely utilize the VDC function—and therefore the rear brake cooling system is recommended. While developed to aid in the necessary cooling for the carbon ceramic brake setup, these kits are also extremely effective in lowering caliper/rotor temperatures for both stock iron rotor setups, as well as the AP Racing iron rotor upgrades. Rear kits include: Polyurethane air scoops, accordion tube, air funnel and mounting bracketry.
