07-10 6.6L GM LMM Duramax S&B Cold Air Intake

Larger than Stock Air Inlet.

Our larger than stock inlet with radiused lip feeds more cool air to the filter. 

Choose your Airflow.

Designed with a secondary inlet that increases airflow. A silicone plug is included for those who prefer to pull in air only from the stock fender inlet. 

Cooler Air. Better Performance.

S&B’s one piece air box design features an integrated box seal that keeps out unwanted engine heat. The cooler the air, the greater the density, resulting in better performance. 

Large Clear Lid with Seal.

Our signature clear polycarbonate lid provides great looks. Featuring a rubber trim that ensures a perfect seal. 

Fit and finish are second to none.

The 75-5091 / 75-5091D intake kit for the 6.6L Duramax installs in less than an hour and outperforms the stock intake.
