Intake Manifold Test! Which LS3 Intake Makes the Most Power?

We hit the dyno hard with Prestige Motorsports as they test three very different intake manifold designs (FAST LSX R, FAST LSX HR and Holley Hi-Ram) against the stock LS3 intake — which is already very good — to see how they perform.

Plus, as if that wasn’t enough, we also had to throw in one of Holley’s 102 millimeter Sniper throttle bodies into the mix. It is horsepower everywhere!
