Pros: Easy to instal, JCwhitney refunded my money.
Cons: Gas mileage went from 15.7 to 12.7 No difference in performance.
"I purchased air filter for a 2000 Jeep Gr Cherokee thinking I would improve performance and gas mileage. There was no noticacble difference in performance, gas mileage went from 15.7 to 12.7. I noticed the difference in my wallet! Listen, you can't put something like this on a vehicle and not expect to re-program the computer and re-tune, your adding more air flow, the computer is going to tell the fuel sensors to add more fuel to balance out the air fuel mix. Plus I had to put up with, I told you it wouldn't work, from the wife! I had no problem with return and refund from JCWhitney. Despite a lousy product(from my point of veiw) I will purchase more products from them."

"I just recently put this on my 02 Dakota. The visual diagrams are a little hard to follow on the one part but otehr than that very clear. Took about 45 minutes to install. Adds a nice rumble in higher RPM's. Makes my exhuast sound healthier. Adds nice look to the engine. No difference in gas millage yet."
