For a Jeep Commander
The unit is pretty simple and actual HP gains are questionable at a stated 12hp. I am sure though, that the Jeep breaths better and overall installation took about an hour. Instructions would be better if pictures were clearer or in color. Otherwise, good product and a little pricey compared to K&N.
Everything I had hoped it would be
My Commander sounds great under acceleration with this installed. I really didn't know what to expect, but I'm pleased. It doesn't sound any different at idle or mild acceleration but step on the gas and for the first time I know I got a Hemi in there! I haven't seen any difference in gas mileage, actually it might have gone down a little, but that might be me stepping on it to enjoy the growl.
