Freedom Air Filters’ pre-filters for Kenworth T880 and Peterbilt 386 and 579 trucks are engineered to offer added protection and extended air filter life without drilling, gluing or removing the intake grilles. The reusable pre-filters are designed to prevent larger particles of debris such as grain chaff, dirt and sand from getting into and clogging the air filter element to help maintain performance and fuel economy. They are treated with a hydrophobic water-repellant process that helps keep out rain, ice and snow and can be cleaned easily with soap and water. Both kits are designed to fit over the factory plastic air intake grilles and come with retainer clips to help facilitate a quick and simple installation.
