Injen Hydroshield black water-repellent pre-filter. Built from a proprietary base media treated with a hydrophobic water-repellent, it diverts dust, water and debris that would otherwise clog the air filter and rob airflow and horsepower. UV- and puncture-resistant with elastic memory that returns it to shape after servicing, it extends the time between filter cleanings. For closed-top air filters. Limited Lifetime Warranty, made in the USA.
