Primary Engine Air Filter Element

Engine air filtration is a critical first line of defense for heavy duty diesel systems, guarding turbochargers, pistons, and sensors from dust and abrasive particulates. The stated element features round geometry with a substantial outer diameter of 377 mm and a height of 203 mm, designed to fit compatible housings without sharp bends or gaps that could bypass filtration. Ultra-Web Nanofiber media provides a high efficiency barrier, delivering 99.99 percent filtration performance under ISO 5011 testing, while maintaining a favorable airflow to minimize pressure drop across operating ranges. The primary configuration and radial seal technology enhance leak resistance during heavy vibration and long service intervals, contributing to more consistent engine performance and reduced maintenance costs. With a capacity advantage over conventional media, this element extends service life and reduces the frequency of filter changes. Cross references DMX P607965 and FG AF26424 connect this part to established OEM specifications, and VMRS code 041-001-001 places it squarely in the air filtration system. Category context 71304 situates it within the engine air filtration family, emphasizing compatibility with compatible Donaldson housings and standard service intervals in demanding on highway and off highway applications.
