The K&N PreCharger DryCharger wrap for E-3380 filters is a red polyester pre-filter designed to extend service intervals in very dusty conditions. Its uniform weave traps small dirt particles while maintaining minimal airflow restriction. Cleanable with K&N Filter Cleaner, the wrap will reduce contaminant loading on the primary filter and lengthen time between services.
