It produced an amazing estimated 32 horsepower maximum increase at the wheels of an otherwise stock 2015 Subaru WRX STi.

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.

I love it
the sound is amazing the installation is easy the results are pretty good
Money well spent
Most bang for your buck... Very noticeable gain in power and the sound is amazing.
I'm very impressed. Very easy and quick to install. Very noticeable power gains. Love the sound of the intake sucking air and the sound of the recirculating valve. Gives the engine bay a cleaner look.
I absolutely love this product. It was very easy to install and made a great difference in the performance of my new vehicle. I have always used AEM products on previous cars I have owned and they have never let me down. This was the best fit, easiest install, and most bang for the buck I have ever had with a cold air intake! Subispeed was great. They processed the order promptly and I received the product only a few days later! I highly recommend!
Impressive Gains/Minimal Work
Took a buddy and I about 30 minutes to install it in my car. Very easy to follow instructions... No need to worry if you're new to working on cars, minimal effort was needed. The blow off valve unloads everytime you hit 3.0psi or higher on the boost gauge, and it is impressive sounding. Definitely worth the investment.
Worth every penny. HP gains you can actually feel, easy installation, and you can finally hear the turbo blow-off valve loud and clear. Best 45 minutes I’ve spent working on my car.
