Injen RD Series Cold Air Intake Subaru 2002-2007 WRX / 2004-2007 STI

The Race Design series intake systems for the 02-07 WRX & 04-07 STI are designed for those Subaru performance enthusiasts in need of more mid-range power. Race Design intakes strategically place the intake air filter in the passengers's fender, allowing for cooler and more dense air to be ingested. Cooler air means more power, throttle response, faster spool and an overall more enjoyable driving experience. By reducing turbulence and providing a less restrictive flow through the high performance filter, each RD intake system is engineered to provide improved horsepower and torque gains over the stock setup. Injen has seen gains of over 14 HP and 17 ft/lbs of torque! Each 6061, T-6 aluminum alloy intake is finished off with an Injen performance dry air filter with built-in velocity stack. Includes stainless steel clamps, high quality silicone hoses, and instructions. Fitment: 2002-2007 WRX 2004-2007 STI
