Cover, Air Filter, Outerwear, For use with WCFab Kits We use and recommend these Outerwears Air Filter Covers for all WCFab air filters used in our turbo kits and intake kits. These Pre-filters are designed to deflect the damaging debris, which can prematurely clog air filters, compromising peak air-flow and horsepower. The Pre-filter also extends the time between servicing intervals for your primary air filter media reducing costs and increasing convenience. - - These Pre-filters contain uniform micron openings and are run dry meaning no additional oils or additives are required. Running a dry Pre-filter means there is no dirt sticking to the oil creating premature loss of airflow and horsepower. Only those particles of dirt smaller than .005" get into the actual air filter, the larger particles simply fall off the pre-filter. In addition, these filter covers are constructed with a woven mesh that is specially treated at the mill using a proprietary process to repel water. This hydrophobic water repellent process is not sprayed on Air Filter Cover Compatible with WCF100717 4" Air Filter and WCF100719 5" Air Filters Enhances the efficiency of performance / exposed air filters Hydrophobic water-repellent treatment UV resistant
