S&B Cold Air Intake for GM / Chevy Duramax

Description

S&B Cold Air Intake for GM / Chevy Duramax 6.6L

This S&B cold air intake for GM / Chevy Duramax replaces the factory airbox with a high-flow intake system designed specifically for 6.6L diesel engines. It delivers increased airflow to the turbocharger while maintaining proper filtration for trucks used in towing, daily driving, or off-road environments.

Built for Duramax platforms, this intake system improves air delivery without introducing airflow turbulence or requiring additional tuning.

Performance & Airflow Design

Factory intake systems often restrict airflow with narrow passages and internal baffling. This S&B setup uses a smooth intake tube and sealed airbox to improve airflow efficiency and maintain stable intake temperatures.

• Airflow increase — Higher CFM capacity compared to stock intake system
• Turbo response — Improved spool characteristics under acceleration
• Load stability — Consistent airflow during towing or high-demand driving
• No tuning required — Works with factory ECU calibration

Filter Options

Choose the filter type based on your driving conditions:

• Cotton Cleanable (Oiled) — Multi-layer performance filter, washable and reusable
• Dry Disposable — High-efficiency dry filter designed for dusty or work environments

Both options are engineered to maintain strong filtration without limiting airflow.
