Banks Power Ram-Air Intake System for 2004-2005 Chevrolet Silverado & GMC Sierra 2500 HD / 3500 (6.6L) - Dry Filter - 42135-D

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

The Banks Power Ram-Air Intake System is engineered to replace the restrictive factory air box with a high-performance, fully enclosed cold-air housing. Unlike "filter on a stick" designs that pull in hot, power-robbing underhood air, the Ram-Air system inhales cool, dense outside air to maximize combustion efficiency. This specific kit features a high-capacity dry filter element, ideal for drivers who prefer a low-maintenance, oil-free filtration solution.

Every Banks Ram-Air system is developed using CAD software and flow simulation before being validated on a flowbench and dynamometer. This kit is uniquely designed with integrated bellows to accommodate engine movement, preventing stress on intake components for a longer service life. Expect significant reductions in exhaust gas temperatures (EGTs) and soot output, alongside improved throttle response.
