Review on 🔥 AEM 21-772C Cold Air Intake System: Enhancing Performance and Efficiency by Brandon Christianson

I just installed this air intake on my 2013 Subaru Impreza Premium 5 speed and overall I'm happy with its performance saving me money on pump and bonus ponies . It seems quieter when idling, but accelerating to 4000 rpm it emits a pleasant growl. Installation took about 3.5 hours but it could have been less if I hadn't been so lazy/stubborn as to remove the passenger side fender. Tightening the hose clamp from the filter cone to the intake tract was a headache but no sweat because I did it and the filter cone doesn't need cleaning for another 100k. Disconnecting and reconnecting the fuel line was a bit of a hassle too. I drive a lot to work, about 180 km a day back and forth on the Autobahn, and I've already noticed how much this increases my fuel consumption. All in all I am very satisfied with this purchase and its performance.
