Stillen Air Intake Kits
Upgrading your vehicle's restrictive stock air box with Stillen air intake kits will allow for increased airflow, which can help your engine breathe better and more efficiently. Air intake systems, also referred to as cold air intakes, are popular performance modifications that can be installed on many vehicle classes, ranging from high-performance sports cars to hard-working diesel trucks. These air intake kit components are designed to replace your vehicle's factory intake assembly with aftermarket intake tubes, air boxes, and filters to overcome restrictions in the intact tract, thus allowing more air to enter the cylinders. With an air intake kit by Stillen, you can expect to see a positive effect on horsepower, torque, and acceleration, as well as improved fuel economy—and that makes Stillen's air intake kits your best dollar-per-horsepower investment by far! Upgrading your vehicle's air intake can provide several benefits, including: * Improved fuel economy—cold air intake systems can improve your vehicle's air-to-fuel ratio, which can lead to better gas mileage. * Better acceleration, cold air intake systems can improve your vehicle's responsiveness and acceleration speed * Increased airflow—upgrading your air intake can allow for increased airflow, which can help your engine breathe better and more efficiently * Enhanced engine sound—increased airflow can create a sought-after engine roar * Better air filter life—aftermarket air intakes often come with washable, reusable air filters that can last longer than standard dry filters * Reduced engine wear—increased airflow can reduce wear on your engine * Engine longevity—upgrading your air intake system can enhance the longevity of your engine

Stillen Rear Brake Cooling Kits
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.
