1994-2002 RAM 5.9L: Banks Ram-Air Intake Review

If you have a 1994–2002 RAM 5.9L, you know that not only is it built tough as an anvil, but owners don’t have to worry about that dreaded heater grid failure happening in newer 6.7L engines. But with all of the modifications and upgrades that you can do to that classic 12- or 24-valve, the best place to start is by improving intake airflow. Most owners put on what we call a “filter on a stick”—an exposed cone filter clamped to the end of a bent tube. That kind of exposed intake draws in power-robbing radiant engine heat from under the hood.

The Banks Ram-Air Cold Air Intake System is engineered to solve that problem: a fully sealed system that draws in cool, dense exterior air to increase horsepower, torque, and fuel economy. Its inlet dwarfs the factory opening, replacing the restrictive flat panel filter with a large, high-flow conical filter element. The oversized inlet, enclosed housing, and larger-diameter ducting reduce flow restrictions, dramatically increasing air mass delivery to the turbocharger. The intake tube geometry was refined using computational fluid dynamics (CFD) software to eliminate internal turbulence. Owners can choose between an oiled or dry synthetic filter element, with an optional pre-filter available for dusty off-road environments.
