thanks wanting to add a better fan, like a mark VIII fan to help with cooling, plus been trying to get a hold of my tuner to switch the on/off fan settings to my 160 stat, but hes never available.
Yeah, you really aren't going to notice anything by upgrading the fans. Get a cooler T-stat and have them come on sooner. That is the best fix if you are running on the hot side. Well, besides an aftermarket radiator, which is a bit extreme for most people.
