I have a magnaflow exhaust system already and wanted to add alittle more noise to it. This CAI gave it alittle more noise, throttle response is much more noticeable, I've driven about 600 miles with the CAI installed and haven't noticed an increase in mpg but that could be because I like the sound of it so I've been having to much fun and not taking it easy enough. Only issue with installation is the vent line didn't fit nice with the intake tube, other than that it was very straight forward.

Sweet sound

This air intake adds a total bad ass sound to my 5.7 Liter HEMI over the stock intake. It does have a little bit more power however since I just put it on last week, I haven't been watch the fuel gauge due to the heavy foot add wanting to hear the sound and power it added. Product was sent exactly as described an I received it the next day. Great buy if you like the power and sound.

Cool Upgrade, Sounds Great, +MPGs.

Installation instructions are pretty straight forward. Sounds great on my Hemi, i did notice some acceleration improvement maybe a little smoother but not a whole lot. The engine does feel better over all mainly the sound. It added about 3MPGs on my jeep which is a plus. And now my engine bay looks a little cooler. Not to mention the weight i lost from the factory intake ;)

i can see my hemi again

I purchased this for my 07 jeep commander 5.7 hemi, absolutely awesome sound and performance, noticed the difference in sound and power instantly, easy to install if you pay attention to steps, as soon as I can keep flooring it I'm sure I'll save a little gas as well.

This is a nice add on. I like the way it looks under the hood. Very nice. Has a nice little whistle to it. Doesnt really help the gas milage out any. It does add a lil hp. Just enough that u can tell a differance.
