I tried a Tymar for a while and liked it. But I did a lot of towing in all kinds of weather and found that in hot temps everything seemed to be running a bit hotter than they did before the Tymar. Hotter enough that the fan clutch was coming on much more frequently than before.
I decided to give the A.I.S. a shot. Combined with the Zoo-dad mod, the temps dropped noticeably. I later added the foam fender-well sleeve and temps dropped even more.
I had to conclude that the underhood, heated air the Tymar takes in was the reason for the difference. The A.I.S. with the Zoo-dad mod takes its air in from the cooler, grille area.
