The K&N DryCharger (PreCharger) filter wrap is a closed-top polyester sleeve sized 6" ID x 6" H that extends service intervals for K&N Filtercharger and similar filters in very dusty conditions. The durable, uniformly woven material stops fine dirt particles with minimal airflow restriction, features a water-repellent treatment that typically lasts one to two years, and is cleanable with K&N cleaner.
