Volvo 21715813 Primary Air Filter — VNL, VNM, VNR, VHD

The 21715813 is a primary engine air filter engineered for Volvo VNL, VNM, VNR, and VHD heavy-duty trucks. Constructed with premium Italian-sourced filtration media, it provides 99% particle capture efficiency to shield turbochargers, cylinders, and pistons from abrasive airborne contaminants. Key Features Radial seal design — 13" OD × 19.5" height for precise OEM fitment 99% filtration efficiency for maximum engine protection High dust-holding capacity extends service life between replacements Expanded outer screen cage ensures rigidity and prevents media collapse Why Air Filtration Quality Matters Diesel engines ingest thousands of cubic feet of air per hour. Without effective filtration, microscopic dust and sand particles act as an abrasive compound inside the engine — scoring cylinder walls, eroding piston rings, and shortening turbocharger life. Replacing your air filter every 12,000–15,000 miles is one of the most cost-effective ways to protect your engine investment. Vehicle Compatibility Direct replacement for Volvo VNL, VNM, VNR, and VHD trucks from 2004 and newer. Cross-references to Baldwin RS4642, WIX 49126, and Donaldson P606720.
