Same product was installed in my vehicle (Jeep GC Ltd, 5.7L Hemi) along with some other aftermarket performance enhancers when purchased... *Warning* It is "Extremely" important to note, that installation is made with a tight secure seal! Bad things will happen if water manages to leak into a loose connection. This time around I used electrical tape as a second measure. Disappointed I haven't received any boost in performance however, my MPG (Mostly HWY) has increased by roughly 12%.

Jet is the way to go!!

Jet chips are worth what you pay for them. You can see a instant power difference. Depends how you drive but you will also see better gas mpgs. I have had 4 of them in different cars and they all worked great. And don't bother looking any other place for them cheaper Autoanything has the lowest price on them and can't be beat.

EXCELLENT

Worth the money for the fuel savings alone.( If you can keep your foot off the pedal) Installation took approx. 25 minutes. Gained 2-3.5 mpg on fuel mileage on the highway and 2 around town. Noticable gain in power also.

I bought the chip along with a K&N air filter to improve the fuel economy of the Grand Cherokee that I recently purchased. It seems to have helped on the Highway as I get around 17/18 MPG but it hasn't done as much to improve the around town driving. I have not really had the car that long, but I am pleased I guess.
