The K&N Drycharger® is a silicone treated, polyester wrap that is made to cover K&N Air Filters or Personal Watercraft Flame Arrestors. These Drychargers, which are similar to the K&N Prechargers, contain uniform micron sized openings that allow high air flow. Yet, due to the Drychargers silicone treated polyester wrap, the amount of water that reaches the air filter or flame arrestor is limited.

K&N RX-4990DR Air Filter Wrap Product Reviews

I got the idea to get this wrap from a fellow employee who has one on his filter and I was sold on how well it keeps the moisture out and it also helps keep the filter clean a bit longer from dust.

The Air Filter Wrap works well. Lets fresh air in even during heavy rain. Air moisture may be high but no problem with the air filter wrap. Fits tight and super easy to install. Like that the color red really stands out and looks great under the hood. Thanx, S.C. Hudgens

Wow Great product, if you have a true Cold Air intake you need this Product as it repels water and keeps your filter dry and it fits perfect on the K&n Filter

Weather in Seattle can be unpredicable, one hour it's beautiful then the next its a heavy down pour. Having the filter wrap around my K&N filter sure did what it was suppose to do and its repelling water. I have a CAI on my Acura Integra. I would fully recommend purchasing this product along with your K&N air filter!! I am definitely buying one for my truck when I have the money!!
