The aFe Magnum FLOW Pro DRY S OE replacement air filter is designed for select 2011–2016 GM diesel trucks equipped with the 6.6L Duramax V8 LML engine. Part number 31-10209 provides a high-flow replacement for the restrictive factory paper filter, helping support improved airflow, horsepower, and torque while maintaining dependable filtration for daily driving, towing, and demanding work applications. Its non-oiled design delivers convenient installation and servicing without the mess associated with traditional oil-based filter media.
Constructed with a 100-percent polyurethane frame, the aFe Magnum FLOW filter is built for long-term durability and repeated use. Three layers of progressive synthetic dry media capture airborne contaminants while providing excellent dust-holding capacity. The tall, open, evenly spaced pleats increase the available filtration area, helping extend service intervals between cleanings. Because the filter is washable and reusable, it can be cleaned and returned to service through multiple maintenance cycles, offering a practical alternative to disposable paper filters.
An integrated polyurethane bump seal is engineered to maintain a tight, no-leak connection within the factory airbox throughout the life of the filter. The progressive seal design helps promote a consistent fit, while the fully polyurethane frame supports reliable performance under the heat and vibration common to diesel truck applications. The filter is compatible with select GMC Sierra 2500 HD and 3500 HD and Chevrolet Silverado 2500 HD and 3500 HD models using the 6.6L Duramax LML platform. Verify vehicle application before installation.
