Also used to use (and still do) ice on the intake after each run. (Cool
Cans work great as well with either dry ice or regular ice w/water.)

Subject: DML: An OLD TRICK with AIR FILTERS
An old trick that I and a bunch of weekend racers used to do to cool down
the incoming air when we raced in Las Vegas was to get a piece of thick
POROUS FOAM and form it (cut or buy) to the shape to go around the outside
of whatever air filter we were using. By thick I'm saying at least 1 to
1/2". What you're doing is making a foam shell to go around the filter
already being used. This foam just before a race is placed in a bucket of
COLD WATER . Just before a race the foam is lightly squeezed out of the
water. What this does--and you guys in the HOT climates know is make an
EVAPORATIVE COOLER for the filtered intake. It drops the intake air down at
least 10 degrees for a 1/4 mile run. To hold the foam onto the filter just
use a couple rubber bands at the top and bottom. Some intake housings can
use just the foam with the way they're made,just make a good snug fit so's
the foam doesn't get sucked into the intake and really plug things up. Once
the race was over,just dunk the foam back into the bucket of water for the
next round. When the race is over just remove the foam altogether and
replace with whatever filter you're running with. Maybe this trick and the
IAT? or whatever that sensor was called may just be the trick for those that
want a cheap 1/4 mile ET. For those that try this trick and they lose
power--too much water is present in the foam and it's plugging up --wring it
out some more until you get the hang of it and what it does. Another way is
to get a K/N type filter(the kind with the cloth gauge with the wire holding
it on and that can also be used without the foam for an even better
benefit,because you wouldn't have to use the foam. A lot of racers who used
this trick put a screen wire over the throats of the carbs so's the foam
wouldn't get sucked into the intake. This trick only lasted a few moments,
but that's all that's needed to WIN.
