Since my transmission coolers and under bumper scoop were so successful--see my award winning expose:
viewtopic.php?f=39&t=8542--I may have gotten a bit cocky. I've gone the full Badger(trek) on my rig in the hopes of getting it to run cooler. I added some large hood vents to get hot air out of the engine compartment and some cool side vents others have used. We shall see...
The hood vents are these:

They are high quality and conform to the shape of the hood, plus they supplied black rivets which look better IMO. Since the hoods are double thickness, I used a white urethane adhesive to glue the inner and outer layers together where I made the cuts.
