Description Banks 42135 Air Intake for 2004.5-2005 GM 6.6L Duramax LLY *Please choose Filter type from option list* The Banks Power Ram-Air Intake System – 42135 is the best way to cool down your 2004.5-2005 6.6L GM Duramax LLY intake air temperatures. 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 underhood engine air, and there’s no power in hot air! Ram-Air houses a giant 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 and mileage, lower EGTs and less smoke. 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! Features Enclosed Housing Keeps Out Hot, Power-Robbing Engine Air Inhales Cooler Outside Air for More Power & MPG Giant Filter Maximizes High-Flow Filtration Helps Engine Run Cooler Prevents Component Damage & Extends Service Life 5-year Warranty (Filter: Lifetime Warranty)
