Upgrade the air intake protection of your GM diesel truck with the aFe Magnum FLOW OE Replacement Air Filter, part number 31-10325-1. Designed for select 2020-2026 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD models equipped with the 6.6L Duramax V8 L5P diesel engine, this performance replacement filter delivers dependable filtration and convenient maintenance for street-driven applications. Confirm vehicle fitment before installation.
The Pro DRY S filter media uses three progressive layers of oil-free synthetic material to capture airborne contaminants without requiring filter oil. Its deep, open pleat design increases usable filtration surface area, supporting strong airflow, efficient filtration, and excellent dust-holding capacity. When service is needed, the filter can be cleaned and recharged with aFe POWER Cleaner, allowing it to be washed and reused through multiple maintenance cycles.
A full polyurethane frame and flexible sealing surface provide a secure fit against the filter housing without separate gaskets or sealants. Polyurethane is engineered to retain its molded shape through repeated engine-bay heat cycles, helping maintain a consistent seal. The included washable foam pre-filter adds another layer of protection by capturing larger debris before it reaches the primary filter media. Its ABS plastic retainer allows the pre-filter to be removed easily for cleaning or quick debris removal between regular service intervals. This combination helps extend service life, increase dust capacity, and maintain airflow in dirty operating environments. Installation is designed as a direct OE-style replacement using the factory airbox.
