Product Description

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.

The pre-filter wrap does what it is supposed to, keeps off water and dust. After washing my car, I can see the beads of water on and dripping off of the pre-filter. I can also see a thin layer of dust forming on it, which is great because it is keeping the service intervals on my K&N filter longer. However, if I remember correctly, K&N states that the pre-filter's water-repelling properties will diminish after two years. That is the only reason as to why I did not give it 5 stars.

This thing is the difference between me being able to drive when it rains/snows or not. The front bumper cover is off my car right now, and the air filter is exposed to the elements far more than it would otherwise be. With this on I can drive in the rain/snow with no problems; without one of these I can not drive in the rain/snow because the filter becomes saturated quickly and the water is pulled through and kills the mass air flow sensor. If your wondering how much of a difference this can make, I am here to tell you it makes a very large difference in the amount of water that gets to your filter.

The main reason I purchased this filter wrap was to prevent large debris from entering the filter pleats. Since this product is specifically manufactured by K&N, I am guaranteed fit, performance, and longevity. The fit is perfect on my filter, not too loose or too tight. The material still allows airflow, but also acts as a "pre-filter" to aid in the cleanliness of the filter. Prior to installing and replacing with a new filter (part RU-4990) I had noticed large pieces of debris embedded in the pleats of the filter, making it difficult to clean. This wrap will prevent such issues and also provide moisture protection as well. Great price and product for protecting your investment.

I was a little skeptical about these water shields, but I figured I'll get one anyway, it'll give me a bit of peace of mind while I drive in the rain. I actually tested it on my hand first by holding it in front of a fan, and surprisingly it does let in most of the air, more than I thought, and it does repel most water as well. I used this on the standard size Spectre filter you get from autozone or O'reily, not the smallest one or the largest one, the one right in between and it fit like a glove.

Bought for the cold air intake on my car. The tubing goes into the fender well and I had lost my fender lining when I bought this. It has since been replaced, but I kept the pre-filter on as an extra layer of protection. I clean it with the filter and it does pick up some crud. It did start to rip on one of the "corners" of the cone filter I have, but not bad. The hydrophobic properties are noticeable.

sprayed down my engine bay with a hose; filter wrap had a bit of beaded up moisture (far less than nearby on hydrophobic coated surfaces). Works as advertised, hopefully will also help stretch my cleaning intervals as I live on a dirt road.

Installation was sort of awkward and dirty (figured I could wait to clean until after it went on), but I managed to install it with the filter in-place.
