Hi anyone out there have any experience with a Rusty's Air Tube hooked to a 4 1/2 X 5 K&N air filter?

i have one on my 05 rocky mountain, with a 9" k&n sounds cool, runs and feels a bit smoother, maybe a tad pappier, and not sure about gas mileage yet

I have the Rustys Air tube on my 02 sport, it was cheap and it works. I upgraded the filter size about a year ago to the 9" k&n as well, increased RPM range as well as fuel econmy!
