Engineered specifically for 2006 through 2007 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LBZ and late LLY codes), the S&B Cold Air Intake System (Part # 75-5080) is designed to minimize airflow restriction while locking out power-robbing engine heat.

Factory intake boxes on common-rail diesels restrict high-volume breathing under demanding towing and performance tuning conditions. S&B resolves this by housing a massive 8-layer cotton cleanable red filter inside a robust, custom-molded air box featuring an industry-first clear top lid for effortless filter condition inspections. Rigorously tested to ISO 5011 standards, this direct-fit intake installs cleanly using factory mounting points with zero core charge.

Key Features & Benefits

• +50.15% Airflow Increase: Significantly outperforms the restrictive factory induction setup, reducing turbo spool lag and lowering exhaust gas temperatures (EGTs).
• Fully Enclosed Air Box: Keeps out loose dirt and hot engine bay air while channeling cool, dense ambient air straight to the turbocharger.
• Clear Inspection Lid: Transparent top plate allows for instant visual checks of filter cleanliness without dismantling the housing.
• 8-Layer Cotton Cleanable Filter: Premium red cotton gauze media provides exceptional filtration efficiency and can be washed and re-oiled for a lifetime of service.
• Zero Core Charge: Brand-new outright performance upgrade requiring no core deposit or core return shipping.
