Freedom Air Filters' pre-filters are designed to prolong the life of air filters on Kenworth T880 trucks.

The pre-filters are designed to offer protection and extended filter life without drilling, gluing, or removing the intake grilles. The pre-filters are designed to fit over the factory plastic intake grilles and the kit comes with retainer clips for a faster installation.

Pre-Filters keep out larger particles of debris such as grain chaff, dirt, and sand from getting into and clogging the air filter element. By keeping out the large particles, air filters stay cleaner for longer, improving performance and fuel economy.

The pre-filters are treated with a hydrophobic water repellent process which helps keep out rain, ice, and snow.  They are reusable and can be cleaned with soap and water.
