Description

The S&B Cold Air Intake system from Stillen is engineered to minimize air restriction and improve airflow for the 3.0L Duramax Diesel engine. For enhanced performance, an additional intake tube is provided to connect directly to the turbo, maximizing airflow. This intake boasts a 51.61% airflow improvement and an impressive 99.24% efficiency rating. The American-made filter is constructed with dry cotton and silicone binders, which are more durable than polyurethane, preventing degradation and air gaps. A clear window panel on the airbox allows for easy visual inspection of the filter's condition. The unique airbox design also incorporates a scoop to capture cool air from the front quarter panel, and includes a removable silicone box plug to offer three different airflow configurations based on user preference and airflow needs. Installation is straightforward and can typically be completed in under 30 minutes using standard tools, with direct connection to the stock intake tube or turbo. The system is compatible with 2020-2024 Chevrolet Silverado 1500, 2020-2024 GMC Sierra 1500, 2021-2024 Cadillac Escalade, 2021-2024 Chevrolet Tahoe, 2021-2024 Chevrolet Suburban, and 2021-2024 GMC Yukon models equipped with the 3.0L Duramax Diesel engine. Please note that this product is not for sale in California.
