I have one, like it.

I *think* it helps, but can't prove it. My stock '91 would get hot at the track, then I replaced the radiator (with thicker aftermarket) and installed the Big Mouth at the same time. I also spent some time blocking off air gaps (seen in picture below) and installed a screen to stop leaves, stones, etc. (not in picture).

When I removed the stock radiator it had a lot of sand and junk clogging it up.
