  • Big gains in Torque and Horsepower

Passes the test. Again and again.
Others build and ship without testing. Not Banks. Our Ram-Air Intakes start out as CAD software prototypes and are put through flow simulations. The design is refined until the simulation shows optimal performance. Then a hardware prototype is made and the design is validated on a flowbench. After that comes dyno testing and on-vehicle testing. It takes a superior design to pass all those tests!

Filter on a stick: a joke that’s not funny.
A filter on a stick is a bad joke. It’s wide-open to hot, power-robbing underhood engine air. Ram-Air houses a giant limited lifetime filter in an enclosed cold-air box, which inhales cool, dense outside air—more than Banks’ competitors and up to 57% more than stock—for more power (up to +39 hp/+69 lb-ft, with tuner). More mileage, lower EGTs and less smoke, too. And it’s designed to not cause fault or error codes.

Bellows, too? Very exclusive.
Banks Ram-Air is the only aftermarket intake with bellows. This accommodates engine movement and prevents component damage for longer service life.
