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-4990DK Air Filter Wrap Product Reviews

Easy order. Prompt shipping. Correct part. Easy fit. Good job.

I recommend getting this item with your filter. You can probably make one yourself out of some material or something, but this will fit right, not come off, and nothing sticks to it. Saves a lot of time and effort when cleaning the filter. I've installed 5 systems on my vehicles since 1998 and put a cover on the filter after the first system and found out how much crap gets deep into the folds. If your going to spend the money on the filter, save yourself and the filter; get the wrap.

It's a much cleaner look with this product on the air filter.

Reduces intake noise and keeps particles and bugs out of the crevasses which significantly reduces your cleaning efforts. I've owned four of these systems on various cars and wouldn't operate without a filter wrap.
