I have peeked at mine and can see where the air enters the fender. It comes
from right between the bumper and the trun signal. As for heat on the
fender, I have driven my truck for a good while on a hot day popped teh hood
and one of the few places that was fairly cool to the touch is the fender
where the air comes in. That's the reason i'm going to go with the k&n setup
(if I don't get rid of it first) and run a tube to the rubber flap. I was
going to use a fluted end and cut a round hole that the end would fit
through but snugly. This way I don't get rid of the flap but still draw in
air there. There is just enough room to run a tube there. It'll be tight but
it will work. I have looked at mine and never removed the flap for this very
reason.
