Key Benefits of Duramax 6.6L Cold Air Intake

• Enhanced airflow for improved engine efficiency
• Strong, high-temperature resistant silicone components
• Options for controlling airflow with secondary inlet plug

Maximum Performance

Our cold air intake minimizes restriction and delivers 29.10% better airflow than the stock setup. The kit includes a fully enclosed airbox that shields the filter from dirt and keeps unwanted engine heat out. As a result, your engine benefits from cooler, denser air, enhancing performance on the road or the track.

Stronger, Longer-Lasting Silicone Parts

S&B uses premium silicone parts that offer a better seal and greater durability compared to standard rubber. This high-quality material handles temperatures up to 400°F without cracking or tearing. Additionally, silicone has a high-friction surface and no oily residue, preventing filters and couplers from sliding off the tube. You can choose between 8-layer Cotton Cleanable or Dry Extendable media for your preferred filtration setup.

Choose Your Airflow

Designed with a secondary inlet, the 2011-2016 Duramax intake allows for even better airflow. If you prefer to pull air solely from the fender inlet, the included silicone plug lets you easily block off the secondary inlet, giving you complete control over the airflow.

Avoid Check Engine Lights

To ensure smooth operation, S&B devotes extensive resources to engineering intakes that work perfectly with your engine's stock calibration or custom tuning. This kit integrates a properly mapped Mass Air Flow (MAF) Sensor, preventing any check engine lights.

Cooler Air, Better Performance

Our one-piece airbox design includes an integrated seal, which blocks engine heat from entering the intake system. By keeping the air cooler and denser, the intake helps improve overall performance, ensuring your vehicle runs at its best.
