Heat rises and you wanna keep your cab cool. Good luck my man!
[quote name='"reddiesel1064"']okay, can someone explain to me what exactly passive intake is?[/quote] Means an open hole where air can come in.....as your fan is blowing out ...this causes negative pressure which in turn causes suction thru the opening at the bottom (passive intake). An active intake would be one that has a blower blowing in air...into the box. So suck air from the top of your box and blow it out ....you now have a passive intake and and active exhaust. Hope that made since....I'm pretty medicated. SignSmoker
