Product Information
Injen Evolution cold air intake for the 2.5L turbo WRX STI with a two-piece roto-molded polyethylene box that includes a boost plenum and an integrated ram air scoop feeding the turbo. The dyno-tuned 6061 aluminum tube in wrinkle red uses patented Air Fusion and MR Technology to hold safe fuel trims without an aftermarket tuner. A large downward-facing SuperNano-Web dry filter seals leak free, no cutting or drilling is needed, and dyno testing shows up to 26 hp and 34 lb-ft on the stock calibration.
