Upgrade your Duramax diesel’s intake system with the aFe Power Magnum FLOW Pro DRY S air filter. Designed for maximum convenience and reliable filtration, this performance filter drops directly into your factory airbox. It features three layers of oil-free synthetic media, providing excellent airflow and high filtration efficiency without the need for filter oil during maintenance cycles.

Built to withstand the rigors of heavy-duty engine bays, this filter is constructed with a 360-degree polyurethane frame that maintains its shape and seal through repeated heat cycles. The integrated 1/2-inch open-cell foam pre-filter provides an additional layer of protection, capturing larger particles and debris in dirty environments before they reach the primary media. Both the Pro DRY S filter and the foam pre-filter are fully washable and reusable, ensuring long-lasting performance and value.
