2008-2017 Freightliner Cascadia Intake Pre-filter Cap

Fits over air cleaner intake with a 13 1/2" diameter.

Protect and extend the life of your expensive air filter with a pre-filter. Pre-filters are designed to enhance the efficiency of any performance or exposed air filter.

The pre-filter is constructed with a proprietary polyester mesh with uniform micron openings, treated with a hydrophobic water-repellent process.

The mesh is UV resistant, filters debris down to .005", is shatter proof in freezing temperatures, and resistant to heat up to 450 degrees.

The material is puncture resistant and has elasticity characteristics allowing the threads to return to the original position in the event the threads have been impacted or shifted.

Pre-filters are designed to deflect the damaging debris, which clogs air filters, compromising peak air-flow and horsepower.
