2011-2016 Duramax LML 6.6L S&B Cold Air Intake

S&B Cold Air Intake (2011–2016 Duramax LML 6.6L)

The S&B Cold Air Intake for the 2011–2016 Chevy/GMC Duramax LML 6.6L is engineered to reduce restriction and improve airflow, flowing 29.10% better than stock. It’s built to improve throttle response and performance while keeping intake temps down.

This kit includes a fully enclosed airbox that protects the filter from dirt and debris while blocking hot under-hood air. Cooler air is denser air — which means better performance.

S&B puts serious R&D into building intakes that function properly on stock tuning or enhanced tuning. This intake features a properly mapped Mass Air Flow (MAF) sensor design to help prevent check engine lights and maintain clean drivability.
