If you read my first post I said do your own research and make your own decision. I'm not going to argue with you about it and lets face it your an amsoil dealer, im sure your partial
I have had k&n intakes on all my vehicles, one was my 430 hp camaro and NEVER had dirt in the intake and I live in AZ so yes it is dusty here, you probablely had a leak after the filter. I pulled the motor apart when I rebuilt the motor and there was nearly no wear anywhere, my cam lobes and crank/rod bearings looked as if they were never even used and that was at 70k miles (thanks to Mobil 1 synthetic)
and a well filterd intake. Im sure the stock airbox/filter would have filterd just as well, but in that case the intake made a definite horsepower increase. In my case with my jeep a CAI is worth the money and an exhaust only compliments it.
The problem is, the CAI either works, or does not. It can't work on your jeep & not mine. My belief that if works on mine & your disbelief about it working on yours has no effect on whether it is actually working or not. The Idea of "making your own decision" is illogical... it's like a light bulb, it is either on or it is off, I may believe it is on, but if there is no current flowing through the element, my belief, no matter how strong, is wrong... the light is off.
The small amount of increase that these manufacturers claim will not be noticed in "seat-of-the-pants" measurements, period. The emotion of the new sound, the thrill of having a new product that cost $100 or more, & the fact that these emotions are causing you to drive more aggressively to "test the results" will provide you with the feelings you want.
The physics are generally this: depending on design, a cold air intake will either have no effect or a decrease in performance at low speeds, & a slight increase in performance at high speeds. If you still have to make up your own mind, take the KJ to a drag strip for time trials. Do it with the stock set up first, then install the CAI, & run it again. You will likely find no measureable difference in results... & if you can't find significant benefits there, you will not have benefits when you go get the groceries.
