We have covered CAI's many times in the past
Lemme just run down the basic tech stuff

and
You can decide about ... appearance
If you are not drawing in cooler air from the outside
then
You won't gain as much hp ... that is when it is coooler
Cool air is dense air thus more hp :Word:
but
If it is hot outside then the gain is minimal or close to none
Bends restrict thus you want NO bends
Metal pipe is thought to be a bad thing due to it getting hot
and
Heating up the temp of air the motor uses
At WOT ... the air is moving by so fast .......
it ain't gonna pick up motor compartment heat or at least .........
it won't be enough to worry about
Again ... We are talkin WOT
You can make your own CAI

with stuff scrounged up at a Home Improvement store for cheap
