The better, cooler airflow should give you 1 maybe 2 mpg better under part throttle operation and up your git-up-and-go when you mash on it.

Exactly what I expect. I already chirp those tires at lights without having to mash the pedal. Surprised me for the 4.0L engine. Didn't think it had that much oomph to it.

I still don't like the automatic tranny. It bangs, hesitates etc too much for my tastes. I shift much smoother on my own.
