Fits select 2007-2010 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD models (6.6L LMM Duramax).

The Banks Power Ram-Air Intake System is engineered to replace the restrictive factory air box on your 6.6L Duramax. By utilizing a fully enclosed cold-air housing and a streamlined design, this system maximizes the intake of cool, dense air to the turbo. This design effectively reduces exhaust gas temperatures (EGTs) and improves both power and fuel economy. The kit features a giant dome-shaped oiled filter that provides superior filtration and higher flow capacity compared to standard filters.

An industry-exclusive 5-inch bellows is included to accommodate natural engine movement during heavy operation, protecting system components from damage and extending service life. Developed through CAD software and flowbench testing, this system is proven to outflow the stock intake by up to 47% and deliver a 5.4% on-highway air density gain without triggering fault codes.
