Once installed the car had more pickup, It sounds great. At idle you can't really hear anything but when you get on it you can hear a distnct difference in the car.

I was skeptical at first about buying a cold air intake. I've researched many web sites regarding performance of intakes. I chose the Injen because it was not a short intake that sat in the engine bay and because of its price. It was worth every penny. I definitely notice the difference in acceleration when taking off from a dead stop. The only complaint that I have is that the metal tube that connects to the throttle body is about an inch too short and the connection is difficult to make.

First off I am not a car guru by any stretch of the imagination. The installation went fairly smooth with the exception of getting some of the hoses tracked down. I could tell the car is more responsive and seems to want to get up and go. The main reason I choose the Injen intake was the sound. And holy jeez it didn't disappoint. It sounds VERY nice. I would recommend this intake to anyone. Excellent product!

Took me a little over 2 hours to install. Instructions were clear. Looks great. Don't notice anything at idle or normal driving. But once you put your foot down it comes to life and sounds great. Not sure about horsepower as car is pretty quick already but I love the much added growl it gives when you ask for it. No regrets. For the price it is a must.
