The K&N Red Drycharger (part 22-2030PR) is a pre-filter sleeve for round tapered K&N air filters, with a 5.25 in base, 3 in top, and 6 in height. Its polyester fabric is silicone-treated, so splashes and mud bead off instead of soaking the filter element, and the wrap also catches fine dirt before it reaches the media. That makes it a practical upgrade for owners who drive through rain, standing water, or dusty trails and want longer gaps between filter cleanings. The manufacturer calls the treatment water repellent rather than waterproof, so the wrap reduces moisture but does not eliminate it. Owners on user forums often describe it as cheap insurance for an oiled filter on a cold-air intake.
Fitment is the main thing to verify. The manufacturer lists this wrap for round tapered filters, so compare your filter's base, top, and height against these numbers before ordering. The wrap is sold on its own, and the package holds one Drycharger. Shoppers searching for a 5.25 x 3 x 6 K&N Drycharger for a round tapered intake filter, a red K&N pre-filter wrap, or a water-repellent K&N filter sleeve for a cold-air intake will find the specifications here.
No. The manufacturer describes the Drycharger as water repellent, not waterproof. It is designed to limit how much water reaches the filter, so a heavy downpour or a deep water crossing can still wet the wrap.
According to the manufacturer, the water-repellent treatment typically lasts 1 to 2 years, depending on conditions and usage.
No. The manufacturer's package listing shows one Drycharger wrap only, so the K&N round tapered filter must be purchased separately.
The wrap is a sleeve, so installation happens off the vehicle: remove the air filter from the airbox, slip the Drycharger over the filter, and then reinstall the filter as normal. The manufacturer says the stitched elastic openings hold the wrap in place, which is why a snug fit matters. Owners on user forums commonly report that the job needs no tools beyond what it takes to open the airbox. Confirm that the wrap's closed top and dimensions match your filter before you start, and check the wrap periodically, because the water-repellent finish wears with use and weather. No product-specific install sheet was found for this part, so consult the manufacturer if your airbox access is unusual.
