When I first installed it, my gas milage went up. It peaked around 23mpg highway. However it has gone down to 19-20mpg highway.

I was wondering, what if you just add an aftermarket cold air filter to the stock air tube? What kinda performance would that have??

I tried that first and I didn't see any noticeable difference. However I didn't have a custom tune then. This spring, I may reinstall the stock air box with the K&N drop in to see if there will be any difference now.

I'm currently looking for an Air Intake kit for my 4.0L V6 engine, Any ideas as to where I can purchase one?

As I was reading, ASULL85 you mentioned re-installing your stock set up but putting the K&N drop (The Head) right? How did that turn out?

I haven't gotten to it yet, unfortunately.
