AEM Cold Air Intake System - Black - 2015-2021 Subaru STI

This intake was measured on a dyno to produce peak gains of 32 hp and 31 ft-lbs of torque.

AEM has created a cold air intake specifically for the 2015 WRX. It produces dyno proven gains!

It 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 their 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.

AEM Cold Air Intake Systems

AEM Cold Air Intakes A cold air intake system relocates the filter outside of the engine compartment to deliver cool air inlet temperatures. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. But that's only part of the power equation. Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows us to deliver large power gains. We also monitor fuel trim correction factors and all OBDII sensors during product development to eliminate leaning the engine out and/or throwing a check engine light.
