Airaid Air Intake System Install - Breathe Easier With More PowerPosted in How To on July 1, 2009
One of the most well-known and easiest exterior engine modifications you can make is upgrading the air intake. It's an easy bolt-on procedure that takes less than an hour (typically) and can net you a few extra ponies by diminishing air flow restrictions caused by factory air intake equipment. Can anyone do it with a few simple hand tools? Yes, even your snot-nosed little brother can achieve this simple modification.
But don't expect that 50hp gain claimed on the side of some boxes. We'll tell you right now that we've dyno'ed countless air intake systems, and the absolute best increase in power we found was 20hp on a 5.3L Chevy V-8. But that is more than double what we find with most intakes-a freak of engineering, no less.
Airaid has taken the air induction game a little further by offering throttle body spacers along with their air intakes. Airaid's offshoot company, Poweraid, brands a line of throttle body spacers with a "helix bore" design that helps spin incoming air to provide a superior atomized fuel mixture (according to its website).
Off Road Evolution placed an Airaid intake and throttle body spacer onto a V-8 Nissan Titan in less than half an hour while we were working on another truck project.
