"The improved engine sound is awesome. Better throttle response, no real increase in fuel economy" —Christopher K from Fort Bragg, NC bought an AEM Short Ram Intake System for a 2004 Acura RSX.
"I installed this in my 04 RSX and immediately noticed a gain in power when I got the RPM's up to 4500. Gives off a nice deep roar sucking in all of that nice cool air." —Joseph G from Staten Island, NY bought a K&N 69 Series Typhoon Intake Systems for a 2004 Acura RSX.
"added the aem cai to my acura rsx. worked great with my turbo and catback exhaust. noticeable increase in mileage and power" —Blair B from San Diego, CA bought an AEM Cold Air Intake System for a 2004 Acura RSX.
"I just installed the intake in my 04 RSX and immedietly noticed a gain in power. it sounds alot different (better) in high revs. it gave my RSX a little bit of power and a much better sound. the most significant change i've noticed was the increase in MPG's. i was getting 33 to the gallon, now im getting well over 40, but take in consideration that i drive it gently and use only BP premium. excellent product, very well worth the money,must have. i wish i thought of this sooner. good luck. (stick with K&N, dont let anyone talk you into those cheaper instore rigged products)" —Mudar A from , bought a K&N 69 Series Typhoon Intake Systems for a 2004 Acura RSX.
"So easy to install! It took me about 30 minutes and the sound and quality of this intake is excellent. Half the price of a true cold air intake and delivers the same sounds and effects in performance. I truly recommend this intake for the people that want a upgrade for their car and don't spend too much money on it either. I love it each and every day I drive my rsx. I LOVE IT!!!!!!:D" —Luis B from New London, CT bought a K&N 69 Series Typhoon Intake Systems for a 2004 Acura RSX.
