Great product. Good horsepower increase, you can feel the difference. Great low tone for optimal sound. Love this product!!!!

Love it.. Have no problems and makes car sound great.

The NGK spark plugs made the feeling of smoother than I can imagine and plus the power. My car got stronger and more fuel efficient.

Great Breaks for the money. Would get again. add in break lines, and this is a even better basic set up.

My opinion of the Injen cold air intake is as follows. I believe it was relatively affordable from this site, almost 50 dollars cheaper from RSXstore.com. The cold air intake does work rather well. I have noticed a difference with low to mid-range power and it sounds cool too. Also I think the store really helps with their customer service options. There are some downsides to this product however. Installation is very difficult, if you are not very familiar with cold air intakes you will have very hard time using it. You have to cut into the wheel well for proper placement. Also you have to cut a piece of metal off of your transmission or else the air pipe will not fit properly rendering the device worthless. All in all this is a good product if you have the time to put it in, but if you don't have six hours to spend maybe go with a short ram intake.
