Banks High-Ram Air Intake Manifold for 2003-07 Cummins

Banks High-Ram Intake An intercooler increases the air density, which allows your engine to produce more power. So it stands to reason that you wouldn't want to restrict the flow of air exiting the intercooler, right? Unfortunately, that's exactly what the stock piece does. See how cramped and angular the factory inlet is compared to Banks' larger, streamlined cast-metal High-Ram. Banks' High-Ram intake flows air much more efficiently, providing greater boost without the drawback of raising turbine backpressure. You'll enjoy improved acceleration and better fuel economy!
