Air Filter
Mack

The Air Filter is a heavy-duty intake filtration solution designed to keep the engine’s air supply clean in demanding environments. A high-capacity media layer captures dust, dirt, and other particulates before they enter the combustion chamber, protecting pistons, cylinders, and turbochargers from accelerated wear. The filter’s outer structure resists collapse under high intake pressures and temperature fluctuations, ensuring consistent airflow during rapid acceleration and long climbs. Regular replacement improves fuel efficiency, reduces emissions, and supports reliable cold-weather starts. For fleets operating in dusty deserts or farm regions, this filter minimizes performance degradation and downtime. Source One Parts Center.
