On my truck, a WAI can aid summer fuel economy, as you are noticing. HP does drop a little. When I did some testing a couple years ago, I saw about a 5-6% increase. I cannot remember the member's name (now I do! Tvago), but he did some testing on a Dakota with a 4.7L like mine, and 130*F was really the upper limit for intake temps. My truck doesn't seem to like it that high, but does show some improvement with IAT above 90*F.
(Maybe my issue is that there isn't enough airflow out of the engine bay since I put in the panel kit...)
