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.

Great fit for both my 1969 John Deere 112 and John Deere 140 with Kohler K241 and K301 engines. Fit perfectly and are cleanable and reusable.

I have enjoyed the K & N replacement filters in all my vehicles for several years. The performance and mileage gains are well worth the investment. I had a '04 Jeep Grand Cherokee with the 4.7 lt V8 and put a full intake kit on that and loved it. When I replaced the Jeep with a '07 Chev Tahoe with the biggest small block V8, the first thing I did was to add the Performance Intake kit. As expected, installation was very easy. Looks great and wow, what a kick. I haven't had a chance to measure mileage yet, cuz I can't keep my foot out of the gas. The sound of that big American V8, breathing thru the K&N kit is awesome. Brings back memories of my heyday with the 60's and 70's muscle cars.The power difference is noticeable immediately. If K&N made a filter kit for my John Deere TRactor, you bet I would have one.

The filter is fine and just as promised. The only reason I didn't give it 5 stars is because it was a really tight fit to get it to go in the filter area. The inside window is just a little too tight. Although it looked exactly the same,I was starting to think that I got the wrong filter because it was so tight. I put some oil on the inside part of the filter and it finally went on. Other than that, no problems. I put it on a 26hp kohler engine, if it makes any difference.
