That is really fascinating how that worked out. What was your base line MPG? In my situation I cannot find any good airboxes to use so I modified a Wrangler CAI enclosure to reduce the IATs. I previously had the filter right on the radiator and IATs were 145ish. Since moving the filter away into the enclosure it dropped IAT to about 130. I think it can get lower since the upper rad hose is touching the boot and maybe seal the filter a bit better.
I got my cruise control module in yesterday so I cam start logging the effect of the filter a bit better and see if what I saw was a fluke.
