There was an interesting debate in another group a while back about
the effects of cool air, something to the effect that the cool air
might be slightly denser but that slightly warmer air allows a better
mix of fuel/air (along the same lines that hot water can hold more of
a dissolved solid). So in theory an engine might have an easier time
making a good air/fuel mix with slightly warmer air.
The argument went on for quite a while but nobody ever came back with
scientific results (dyno tests, etc) so no meaningful conclusion could
really be reached from the debate.
Personally, I'd leave things the way they are as it should provide
additional protection against things like sucking rainwater into your
engine.

Re: REQ: Stupid air intake question
I believe they finally got smart and closed off that water ram chute
because of too many blown engines.
Some earlier ones had that opening hooked up so when you hit any kind of
water puddle and the water splash came above the bumper, the engine
inhaled it and hydrolocked. This blows pistons, connecting rods,
cranks, etc.
If you think about how many times water makes it up onto the hood of a
Cherokee when puddle jumping.... Then if you try a creek crossing,
well.....
Some YJ's has this water ram chute hooked up too so they have to be
really careful off road or disconnect the thing before hitting puddles.
I have been with one that hydrolocked because of it. he was very lucky
he was going slow.

Re: REQ: Stupid air intake question
Of course, you know the Environmental Protection Agency mandates
the air intake to be forward of the radiator cross member on all their
SMOGed vehicles for the last thirty years, solely to improve gas
mileage. My '78 Bronco: http://www.----------.com/freshair.jpg And if
you ever popped the box holding your clogged air filter, you'd see it's
intake is forward of the cross member, too.
