Yes, the wire mesh should face up..
Yup, the wire mesh should face outward, so the
side that says AMSOIL is on the dirty side.
And you will get some filter oil drainage, but
I doubt there is enough to cause problems in
the intercooler. Do take the time to blot out
as much excess oil as you can.
I removed the rubber tube connecting the airbox
to the fender. It appears to be more of a noise
supressing tool than anything else. It could also
reduce the possibility of water injestion into the
airbox, so if you do a lot of 4 wheeling or deep
water crossing, maybe leaving it in is a good
idea. .
On the other hand, if you are
worried that removing it will allow underhood heat to decrease the
power output of the engine, remember that the
turbo compresses the intake air to 19 PSI or more
and that creates a LOT MORE heat. The intercooler
is there to remove that heat buildup. Next time
you pull in for fuel or pop the hood for some
reason, feel the intercooler with your hands on
either side (near the left and right headlights)
and you will notice the passenger side feels quite
warm and the driver side is much cooler.
Hope this helps!
