New external pre-filter

Freedom Air Filters says its external cleaner pre-filters are engineered for installation over the top of the intake grille, which helps prevent large particles of debris such as grain chaff, rubber, dirt and sand from getting into and clogging the air filter element.

The reusable pre-filters are treated with a hydrophobic water-repellant process to help keep out rain, ice and snow. They are fastened over the intake with elastic to facilitate quick, easy installation and are cleaned easily with soap and water, the company says.
