Injen Technologys Hydroshield are designed to enhance the efficiency of any air filter, including Injens SuperNano-Web and their 8-Layer oiled cotton gauze air filters. Injens Hydroshield is constructed from a proprietary base media and then treated with a hydrophobic water-repellent. Injen's Hydroshield is UV resistant, can stop contaminants down to .005, is puncture resistant, and has elasticity characteristics which helps the Hydroshield to return to the original shape/position after servicing. Injens Hydroshields are engineered to divert damaging contaminants, which can clog your air filter and compromise peak air-flow and horsepower output. Injens Hydroshield also extends the time between servicing intervals, reducing costs and improving the overall user experience.
