Injen Hydroshield is engineered to augment the efficacy of any air filter, encompassing Injen's SuperNano-Web and 8-Layer oiled cotton gauze filters. Constructed from a proprietary base material and treated with a hydrophobic water-repellent, the Hydroshield is UV resistant, impervious to contaminants as small as .005 inches, puncture resistant, and elastic for shape retention post-servicing. By deflecting harmful contaminants that can obstruct air filters and diminish airflow and horsepower, the Hydroshield extends service intervals, reducing expenses and enhancing overall user satisfaction.
