"Brings look & a little better performance for a reasonably priced upgrade. Delivery was on time & shipped in original AEM box unopened. Installed in my son's first car 03' Acura RSX & both he & I are more than pleased. Came complete with easy to understand step by step instructions & fit perfectly under the hood. I would recommend Auto Anything to others & will check on additional upgrades for this car. Thanks Auto Anything!" —Larry C from Fresh Meadows, NY bought an AEM Short Ram Intake System for a 2003 Acura RSX, Base model.
"Installed this on my base rsx, easy to install. Did it on my lunch break at work, took about 15 mins total. I could feel the difference as soon as i started it. The best quality thing is the kn filter, the tubing seems tiny and scaried the weld bracket will break if i hit a bump to hard." —Chris C from Clinton, MA bought a K&N 69 Series Typhoon Intake Systems for a 2003 Acura RSX, Base model, 2.0L 4-cyl. engine.
"I immediately installed my V2 and took it out for a test run and felt the power. On my first run I had 470 additional Lbs. in guest in the car and I still felt more power then with just me stock.
My second run I went by myself and got lots of wheel spin when hitting second gear in addition to the first. The power was nice. Beware I have read reviews that when you are in hot weather you actually lose hp. I took it out at night so I have yet to experience that." —Simeon E from Fresno, CA bought an AEM V2 Cold Air Intake System for a 2003 Acura RSX, Type S, manual transmission.
