There is minimal difference between cold and not cold Air intakes. especially on a DD car.
Now, I've seen drag racers that pump ice water throught their intercoolers to bring air temps down. But again those guys are looking for hundreths of seconds.
FWIW.

I'd say that 20 degrees F is fairly significant here.
PV=nRT. Pressure x Volume = Amount of air x some fancy constant x temperature
Now, we can assume that pressure is constant, and we're talking about a fixed volume of air so thats constant too. And the constant is ... I don't need to explain that one, do I?
So lets re-write that equation for our situation
n
1/T
Now, going from 70F to 90F means that your air temp has increased by 4% (relative to absolute zero). So if it goes up by 4%, then the amount of air has gone down by 4%, and consequently you're engine power will be down by a similar percentage.

it looks cool.... till you have to perform.

Speaking from experience with sock stuffing?
