Racers have been cooling fuel forever.

It has the benefit of lowering intake air temps which in turn lets you run more timing. In fact, I would expect in the above dyno charts that pre-mod, the ECU was pulling a small amount of timing due to intake air temp.

There are several styles available.

Passive:

I've seen some active ones with fans too. The best placement seems to be on the return side as it's generally lower pressure.
