So every time I clean my filter, which is every 2 rides, and I replace it every month, I'm always in disgust about how nasty the air-box is with mud and dirt. Some dry and some wet. Its such a pain to cover the hole with a dirty towel just so I can spray some cleaner all down in there and try to scrub it by hand & finger. Now I can just spray it out with a hi-powered hose!!! stays spotless!! I leave the cover on til it drys up enough to put the filter back on, crank the bike, and let the motor dry the rest!!! Awesome tool!!! Thanks, I tell my riding buddies about this!!! Good product, simple but works!
