I've got all but about 1 of the openings blocked right now. Great for winter time warm up. So far I haven't had any problems with it getting too hot. Summer time I had 4 of the openings blocked and the only time it kicked in the fan was when we saw temps over 95F with a lot of stop and go in town driving(then again what car won't). Haven't seen a drop in mileage. I've done several mods at once so I'm not sure how much it improved it. But I do remember after putting them in I noticed it pick up speed faster going down hills. So I guess my butt dyno says its helping.
