"Sound was GREAT and loved the performance boost! Easy to install!" —Kwok Wai W from El Monte, CA bought an Injen SP Series Cold Air Intake for a 2004 Acura TSX.
"With the usable power band on the 2.4L Honda inline 4 being biased towards higher revs, I was looking for something to bring more power to the low end. If you're looking for a significant horsepower increase, you won't see it with the Injen SP, but it definitely fattened out the mid range on my 04 TSX. My torque band shifted down about 1,000 RPM to 3,100 (roughly), which is a nice improvement. Then there's the sound... When you drive a Honda, you worry about coming off ricey in a world full of ricers with coffee cans for exhaust tips, but the Injen SP brought out a deep growl I didn't know my four banger had in it. I'm very satisfied--though the sticker on this bad boy is a little stiff. Its ability to convert to a short ram makes up for some of the cost, though." —Erik B from Mundelein, IL bought an Injen SP Series Cold Air Intake for a 2004 Acura TSX.
"I own a 2004 Acura TSX and purchased the AEM Short Ram Intake for it. The intake installed in under 30 minutes and the fit was perfect. The performance increases have been great, as advertised. I do recommend the following tips for installers:* when removing the OEM air box, there is a wire harness that is attached and the zip tie will have to be cut (*be careful to not cut any wires, just the zip tie)* when attaching the oil coupler to the air intake shaft a more secure clip may be needed to keep it in place* please note that the air filter version is AEM's new dry flow technology (*make sure to order the correct filter cleaner)**please note all of the above installation tips are for the 2004 Acura TSX version of the AEM Short Ram Air Intake System" —Mark R from Hudson, MA bought an AEM Short Ram Intake System for a 2004 Acura TSX.
