Pros: Sounds good, easy install,
Cons: Expensive, minimal gains
Comments: Im sure if you found this unit for less than I paid it would be a better deal.
As with all K&N intakes I've dealt with, removing the stock air filter and assembly is more time consuming than installing the K&N kit. Installation instructions are simple, and have pictures, should you require them. Everything is bolt on and thus can easily be returned to stock if you were selling the vehicle. I have mine on a 02 WJ Grand Cherokee 4.0L
I have yet to take another long highway trip to see if fuel economy has improved.
Minor acceleration increase noted.
