I'm looking for an airbox block, so when I wash my bike, I can remove my air filter and the air intake can be blocked. I seen one in a No Toil movie, but can't seem to find one online. I'm possibly calling it the wrong name, and need a proper name in order to find one. The one I saw in the No Toil movie was a rubber flap that basically covered the air intake hole from the airbox. This way I don't have to fear water is entering my engine when I wash.
