Banks Ram Air Intake System for 6.6L Chevy/GMC Duramax

Superior Design.
The stock system is highly restrictive. The cramped outlet has tight bends, the filter design is inefficient with minimal filtering area, and the air that it does draw in is warmer and less dense. The Banks Ram-Air Intake System is “clean-sheet” engineered to minimize restriction, maximize flow and filter area, and draw cooler, denser air from outside the engine compartment.

Superior Performance.
There’s a smokescreen of inflated power claims out there. But at Banks, they deal in facts, not fiction. Banks’ standards are rigorous, and all testing is conducted under exacting conditions with documented results. Who needs hype when you’ve got the truth?

Superior Quality.
The Banks Ram-Air Intake System is engineered for long-lasting performance, tough-as-nails durability and factory reliability. For example, Banks’ design includes bellows, which allows for engine movement, protecting the turbo and promoting longevity.

Designed, developed & tested by world-class automotive engineers.
The most durable and reliable cold-air intake system on the market, Banks Ram-Air Intake System will out-live your diesel!
