Banks Power 04-05 Chevy 6.6L LLY Ram-Air Intake System

Gain up to +39 hp/+69 lb-ft. Reduces exhaust gas temps (EGTs) and smoke. Outflows stock and competitors up to 35 percent. 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 filter in an enclosed cold-air box, which inhales cool, dense outside air—more than Banks' competitors and up to 35% 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. Key Features: Enclosed housing keeps out hot, power-robbing engine air. Horsepower gain up to +39 hp and +69 lb-ft of torque. Extends service life and requires fewer cleanings. Inhales cooler outside air for more power & MPG. Reduces exhaust gas temps (EGTs) and smoke. Outflows stock and competitors up to 35%. Giant filter maximizes high-flow filtration. Accommodates engine movement. Prevents component damage. Helps engine run cooler 5-year Limited Warranty.
