The stock intake draws air from the front grill and I would
call it a cold air intake (with some plumbing to draw in
warm air for cold starts and warmup). Some cars fitted with
the cold weather package have a plastic part that blocks the
opening a bit (keep water out from big puddles). Might check
at the front of the grill for this and if you don't need it
in your area you could remove it (if you ahve it).
