2011-2016 Chevy/GMC Duramax LML 6.6L S&B Cold Air Intake (Cleanable Filter)



Product Information

In this era of high-cfm gas engines and air-hungry diesels, S&B test their filters to Standard ISO 5011, which has produced exact and repeatable results. Due to the controlled test setting, performance certificates now accompany S&B filters for added assurance.

S&B filters are also submitted for CARB approval; most are approved while those with the newest engineering innovations await approval. Made in U.S.A.

Large Silicone Filter with 5″ ID opening.
Silicone’s elasticity allows for a superior seal on the intake tube. With no oily residue, the filter won’t slide off the tube or require you to wash your hands. Our Silicone filters and couplers can endure temperatures up to 400F without cracking and boasts high tear strength.

Cool Air, More Density.
Our huge intake scoop engulfs more cold air. The cooler the air, the greater the density, resulting in better performance.

Clear Lid with Seal.
Signature clear S&B lid now features a rubber trim that ensures a perfect seal.

Quick and Easy Installation.
Metal brackets allow for easy installation of the new air box by using the OEM air box mounting locations.

Optional Secondary Box Opening.
Designed with a secondary inlet, further resulting in even better airflow. A silicone plug is included for those who prefer to pull in air only from the fender inlet.

Low Restriction Intake Tubes.
Intake tubes are designed for smooth air flow and less restriction.


  • Airflow Rating: Flows 41.8% Better than the Stock Intake
