Outerwears pre-filter water-repellent cover for open-ended air filters (Green Filter, K&N and more - TiVCT Focus/EcoBoost Focus ST/Focus RS/EcoBoost Transit Connect/EcoBoost Escape)

Outerwears 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 an optional hydrophobic water-repellent process. The mesh is water-repellant, UV resistant, filters debris down to .005", is shatterproof 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. The manufacturing process incorporates a welded seam for strength or reinforced industrial grade thread to fill needle holes and to reduce potential failure points in the material. The top seam utilizes specialized thread and cording to reinforce the durability of the top. Pre-filters are designed to deflect the damaging debris, which clogs air filters, compromising peak air-flow and horsepower. The Pre-filter also extends the time between servicing intervals reducing costs and increasing convenience for the consumer. Custom designed cover for aftermarket filters such as Green Filter, Cobb Tuning, KN, Roush, Mountune that do not already have rain cap in place.
