The Injen Hydroshield Black (Part No. inj1118BLK) is designed to protect and extend the life of your air filter by diverting damaging contaminants that can clog your filter and reduce performance. Constructed from a proprietary base media treated with a hydrophobic water-repellent coating, this shield offers exceptional resistance to water and waterborne particles while maintaining flexibility to return to its original shape after servicing.
Ideal for use with Injen's SuperNano-Web and 8-layer oiled cotton gauze air filters, the Hydroshield is UV resistant and puncture resistant, ensuring long-lasting durability under various driving conditions. Its design helps maintain peak air-flow and horsepower output by preventing dirt, water, and other debris from reaching the filter, thus improving overall engine efficiency. The shield's dimensions make it a perfect fit for many Injen air filters, especially the Injen X-1093 model, providing a direct fit that simplifies installation and removal.
The Hydroshield's hydrophobic treatment helps repel water (note: it does not make your filter waterproof), making it suitable for different weather conditions and environments. Its elasticity allows it to return to its original shape after cleaning or servicing, ensuring a snug fit that consistently protects your air filter. By reducing the frequency of filter replacements, the Hydroshield not only saves money but also enhances your vehicle's performance and reliability. Proudly made in Pomona, California, this product is backed by Injen’s limited lifetime warranty, reflecting confidence in its quality and durability. Whether you're looking to improve your vehicle's airflow or extend the service interval of your filters, the Injen Hydroshield is an essential upgrade for serious enthusiasts and everyday drivers alike.
