Are you replacing a worn or clogged air filter to restore proper airflow and protect your Duramax engine? The MAHLE Air Filter is a high-quality OE replacement designed to prevent dust, dirt, and debris from entering the engine’s intake system. Maintaining a clean air filter is essential for efficient combustion, improved fuel economy, and engine longevity. Whether you are performing routine maintenance or replacing a dirty filter, the LX 5211 helps ensure your engine receives the clean airflow it needs for reliable performance.

Manufactured to meet strict OE specifications, the MAHLE LX 5211 uses high-efficiency filter media designed to capture up to 99.9% of dust, soot, and airborne contaminants, helping protect critical internal components such as piston rings, cylinder walls, bearings, and valves from premature wear. Its pleated media design provides a large filtration surface area and strong dirt-holding capacity while maintaining consistent airflow to the engine. MAHLE air filters are built for durability and install directly into the factory airbox for a precise, drop-in fit during regular service intervals
