I will most likely be going with a pfab or precision intercooler to support 700hp and my concern is the fitment and efficiency. A lot of the intercooler will be hiding up and behind the bumper and won't be exposed to the air flow like it should be. Does the front bumper need to be fabricated to allow for full Air exposure or does it not matter that a good 6-8"/40% will be blocked behind the bumper? For those who are covering up most of their intercoolers, did you notice any efficiency issues? Thanks.
