Banks Power Ram-Air Cold Air Intake System for 2004-2005 Chevrolet Silverado & GMC Sierra 2500HD/3500 (6.6L LLY)

Fits 2004-2005 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 models (6.6L LLY Duramax).

Replace the restrictive factory intake on your Duramax with the Banks Power Ram-Air Intake System. Unlike "filter on a stick" designs that pull in hot underhood air, the Ram-Air system features a fully enclosed housing that draws in cooler, denser outside air. This CAD-designed and flowbench-tested system outflows stock equipment by up to 35%, resulting in significant performance gains and lower exhaust gas temperatures (EGTs).

Engineered for longevity and reliability, this kit is the only aftermarket intake to include integrated bellows. These bellows accommodate natural engine movement during torque load, preventing stress on intake components and ensuring a longer service life. The system includes a high-flow oiled air filter element designed for maximum filtration and extended service intervals.

• Design: Enclosed cold-air box prevents heat soak and reduces smoke/soot
