Air filter for Mack tractors

Freedom Air Filters says its new pre-filter pair for Mack’s CH and CL models is engineered to prevent larger particles of debris such as grain chaff, rubber, dirt and sand from getting into and clogging the air filter elements.

These pre-filters are treated with a hydrophobic water-repellant process that help keep out rain, ice and snow and are designed to protect a truck’s engine and performance air filter without sacrificing airflow or horsepower. Freedom Air Filters say they are configured to fit directly over the factory air intake grilles and to be installed easily by removing and replacing two screws and by using the provided washers.
