Banks Ram Air Cold Air Intake Fits 2004-2005 Chevy / GM 2500 3500 6.6L Duramax

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. The optional high-flow Super-Scoop is another Banks exclusive!Enclosed housing keeps out hot, power-robbing engine airHorsepower gain up to +39 hp and +69 lb-ft of torqueOptional Super-Scoop rams cold air for more powerExtends service life and requires fewer cleaningsInhales cooler outside air for more power & MPGReduces exhaust gas temps (EGTs) and smokeOutflows stock and competitors up to 35%Giant filter maximizes high-flow filtrationAccommodates engine movementPrevents component damageHelps engine run cooler5-year Limited WarrantyOILED Air Filter ElementCARB E.O.
