I have tried in the past, both a "Tymar" style open filter element and a fresh air style Ford AIS.
I found that especially in the summer and while towing, the AIS allowed things to run noticeably cooler. This was compared to the open element style which drew in under hood air.
The AIS has an intake snorkle that goes forward towards the grille area. Used in conjunction with a "zoodad" mod, the intake air is about as fresh and cool as you can get.
I'm not that familiar with some of the other intakes. But I've seen some open element types with a "box" and intake which intakes fresh air from the grille area. I'd look for something with that fresh air feature.
