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 with Dry Filter (Part # 75-5080D) is tailored for drivers operating in heavy agricultural, off-road, or dusty conditions where synthetic dry filtration is preferred over oiled cotton media.

The system features a custom-molded, fully enclosed air box that isolates the air charge from under-hood engine heat while sealing out loose dirt. Equipped with S&B's industry-first clear top inspection lid, this kit allows users to check filter condition instantly. Rigorously tested to ISO 5011 standards, the 75-5080D installs seamlessly using factory mounting points with zero core charge.

Key Features & Benefits

• +50.15% Airflow Increase: Outflows restrictive factory airboxes significantly, decreasing turbo spool times and lowering exhaust gas temperatures (EGTs).
• Oil-Free Dry Extendable Media: Advanced synthetic dry filter media captures fine particulate matter in dusty environments and can be cleaned easily using compressed air.
• Fully Enclosed Air Box: Prevents hot engine bay air and dust from entering the intake tract, ensuring dense, cool oxygen delivery.
• Clear Top Inspection Window: Provides effortless visual checks of filter condition without requiring disassembly.
• Zero Core Charge: Brand-new outright performance upgrade requiring no core deposit or core return shipping.
