Just purchased the Banks Ram-Air cold air intake for my 2002 4.0/I6 TJ X and a street and performance helix power tower plus throttle body spacer. I'm gonna install in the next few days, but was just curious if anyone out there has used these two items and what you thought about them, specifically the Banks kit? I had Airaid intake and spacer on my V8 02 Grand and noticed a difference in power and 2 mpg gain.
