Product Description

The Banks 42142 Ram-Air Cold-Air Intake System is a high-flow upgrade designed for 2006 and 2007 Chevy Silverado and GMC Sierra 2500HD/3500 trucks equipped with the 6.6 L Duramax diesel engine (LLY/LBZ variants). This cold-air intake replaces the restrictive factory airbox and tubing with an enclosed Ram-Air design that draws cooler, denser outside air into the engine - helping improve combustion efficiency and overall performance.

Featuring a large filter element and streamlined housing, this intake system significantly increases airflow and air density compared with stock, which can enhance power, torque, and throttle response while also lowering exhaust gas temperatures (EGTs) and reducing sooty black smoke under load. A flexible bellows section accommodates engine movement without stressing components, and the system is available with either an oiled or dry filter element to suit your maintenance preference. Direct bolt-on installation with included hardware makes this intake a straightforward performance upgrade for compatible Duramax diesel trucks.
