Upgrade your Chevrolet Silverado 2500HD or GMC Sierra 3500HD with the S&B Air Intake for the Duramax L5P 6.6L engine. Delivers up to 47.70% better airflow with a fully enclosed airbox that protects against dirt and heat for improved performance.

Protect Your Engine

The S&B Cold Air Intake comes equipped with a massive, high-efficiency air filter that enhances engine performance while providing superior protection. Choose between the 8-layer Cotton Cleanable filter or the Dry Extendable media for top-notch filtration and durability. This robust filter setup ensures your engine remains clean and performs at its best.

No More Check Engine Lights

Our intake system is engineered to work seamlessly with both stock calibrations and enhanced tuning, avoiding check engine lights. The intake kit features a precisely mapped Mass Air Flow Sensor, ensuring your engine runs smoothly without triggering warning lights.

Silicone Integrated Scoop

The L5P intake kit includes a silicone air scoop that integrates directly with the system, delivering even more air to the filter. This feature enhances airflow and contributes to better overall engine performance.

Multiple Air Inlets

To maximize airflow, the L5P intake kit includes two large air inlet points. For customization, an optional box plug is provided to seal off one inlet point, allowing you to adjust the airflow based on your specific needs. Removing the plug is ideal for additional performance upgrades, while keeping it installed helps protect against excess engine heat and debris.
