Air Filter
Mack

This heavy‑duty air filter is designed to deliver clean intake air to the engine, protecting internal components from abrasive dust and particulates. A high‑capacity filter media provides strong filtration efficiency with low pressure drop, helping to sustain engine power and fuel economy in challenging dust conditions common to commercial fleets. The pleated design maximizes filtration area, extending service intervals while maintaining consistent flow even as dust loading increases. A clean air supply reduces cylinder wear, minimizes the risk of pre‑ignition, and supports reliable cold starts in varying climates. The filter media and seals are chosen for compatibility with Mack engines, ensuring a tight seal and resistance to moisture ingress. Regular replacement according to service schedules is essential to maintain peak engine performance. For fitment confirmation and replacement guidance, contact Source One Parts Center.
