Description

AEM intakes has once again stepped up to the plate with cold air intake (CAI) 21-735WB, and produced an amazing estimated 32 horsepower maximum increase at the wheels of an otherwise stock 2015 and 2016 Subaru WRX STi. Dyno testing on the 21-735WB cold air intake was performed to back our substantial claims of increased horsepower. AEM dyno tests prove that this CAI produced an estimated maximum gain of 32 horsepower @ 5400 RPM and an estimated increased in torque of 31 lb-ft @ 5400 RPM.

The AEM cold air intake design for the 2015 and 2016 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 AEM 2015 and 2016 Subaru WRX STi cold air intake Dryflow filter is washable and reusable. An AEM dry filter uses a synthetic air filter media and does not require oil which allows for quick, easy cleaning. An application specific powdercoated aluminum heat shield is included in the AEM CAI for the 2015 and 2016 STi to help prevent engine heat from increasing the inlet air temperature. "Excellent air inlet temperature management ensures consistent and reliable power," says product engineer John Concialdi.

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-black powdercoat finish to ensure the AEM cold air intake will look just as good as it performs. The wrinkle-black powercoat finish is being offered as an alternative to the wrinke-red version, number 21-735WR, for 2015 and 2016 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.
