The K&N Universal Round Tapered Filter Wrap, part RE-0810PK, is a black wrap for round tapered air filters, listed at a 6-inch base inside diameter, 4.625-inch top inside diameter, and 9-inch height. K&N's install sheets for several of its filters note that Drycharger wraps are sold separately from the filters they fit, so this wrap works as an add-on accessory rather than a replacement filter element. Adding a wrap gives a tapered element an extra outer layer to catch dirt, which can be serviced separately from the filter itself.
Choose this wrap over running a bare tapered filter when you want added dirt protection in a dusty environment, such as dirt roads, gravel, or track days. Because it is a universal design, the fit depends on the match between the wrap's base and top diameters and your filter's own dimensions. Measure your filter before ordering, and confirm the height works with your intake setup. Owners looking for a custom wrap for a specific vehicle should check the manufacturer's application listings first.
