Banks 42132 Air Intake for 2001-2004 GM 6.6L LB7
*Please choose filter type from option list*

The Banks Power Ram-Air Intake System – 42132 is the best way to cool down your 2001-2004 6.6L GM Duramax LB7 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!
