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!
