AEM intakes has once again stepped up to the plate with the release of their cold air intake for the 2015 Subaru WRX STI (2.5L). This intake produced an amazing estimated 32 horsepower maximum increase at the wheels of an otherwise stock 2015 Subaru WRX STi. Dyno testing on the 21-735WR cold air intake was performed to back AEM's substantial claims of increased horsepower. AEM dyno tests prove that CAI, number 21-735WR, produced an estimated maximum gain of 32 horsepower @ 5400 RPM and an estimated increased in torque of 31 ft-lbs @ 5400 RPM.
The AEM cold air intake for the 2015 Subaru WRX STi positions the AEM Dryflow Air Filter in a location near the front of the car to help pull fresh air from outside the engine compartment. Bringing in cooler outside air can result in more power. The AEM synthetic Dryflow air filter is designed for low restriction without compromising engine protection. The 21-735WR 2015 Subaru WRX STi cold air intake Dryflow filter is washable and reusable. An AEM dry filter uses a synthetic filter media and does not require oil allowing for quick, easy cleaning. An application specific powder coated aluminum heat shield is included in the AEM CAI for the 2015 STi to help prevent engine heat from increasing the inlet air temperature.
A mandrel bent aluminum air intake tube is utilized to direct cool intake air smoothly from the AEM Dryflow filter and into the turbocharger. This aluminum intake tube is protected by a wrinkle-red powder coat finish to ensure the AEM cold air intake will look just as good as it performs. The wrinkle-red powder coat finish was chosen in order to match original equipment parts visible under the hood of 2015 Subaru WRX STi models. The entire AEM cold air intake, as well as the AEM Dryflow air filter is backed by the AEM limited lifetime warranty.
