The K&N RF-1032DK is a black, round tapered Drycharger wrap made from silicone-treated polyester with stitched elastic openings. It fits over the outside of a round tapered air filter as an extra pre-filter layer. The wrap is made to cover K&N air filters, and its durable silicone-treated polyester uses stitched elastic openings. Its micron-sized openings let air through while catching grit before it reaches the filter element. The silicone treatment helps keep splashes and mud from soaking the filter. The manufacturer stresses that the wrap is water repellent, not water proof. Choose it for wet-road spray, puddle splash, and dusty trail or track days, not for submersion. The wrap adds minimal restriction to the airflow of the filter. A bare filter also wears faster in grit, so this wrap can stretch cleaning intervals on a dusty-road or off-road setup.
Fitment depends on measurements, so check your filter before buying. The manufacturer lists a 6.5-inch base inside diameter, a 4.5-inch top inside diameter, and a 7-inch height. Search terms like "round tapered air filter pre-filter wrap 6.5 base 4.5 top 7 inch" and "K&N Drycharger RF-1032DK water repellent" will find this part. The manufacturer's water-repellent treatment repels water for up to 1-2 years, which makes it a practical upgrade for owners who want to stop cleaning or replacing filters so often. Installation is a simple slip-on job, with no tools or wiring required.
The manufacturer lists this as a round tapered wrap identified by its dimensions, with no vehicle application given. Confirm that your filter measures 6.5 inches at the base, 4.5 inches at the top, and 7 inches tall before ordering.
The manufacturer lists this wrap as open top, meaning it is not a closed-top design.
The manufacturer states that the water-repellent treatment typically lasts 1 to 2 years. The wrap repels water but is not waterproof.
