5 Star Review

I just put your K&N intake kit on my wife's 2004 Impala SS LE with a supercharger and the response is unbelievable. Not only is it much QUICKER, it gets 3-4 mpg. My wife was a little skeptical when I told her what I was doing, but now she loves it. She handles the car very well for a 70 year old grandmother. Thanks again and keep up the good work.

5 Star Review

I absolutely LOVE this product!! It really begun to 'wake up' the 3800 Supercharged V-6 in my '04 Impala SS! It just goes to show you how restrictive the stock intake really is. I can actually feel the HP gain especially off idle, it feels so much more responsive. Install time was about an hour and a half like the website states. Not sure how the fuel MPG improved yet since I haven't driven a full tank of gas. I do recommend this product ESPECIALLY for anyone with a factory supercharger/turbo charger.

5 Star Review

Purchased kit for 2002 Grand Prix with 3.8L with over 100,000 miles. Installation was easy and directions very good. Fuel mileage in town increased almost three miles per gallon. Engine response is very good. Waiting for the F150 for the 3.7 liter v6 to become available so I can install on my pick up. Nice clean installation and have no problems.
