Tried it out first time on my 06 crf250r and it leaked water all into my intake, carb and motor. Very poor product. However no-toil sent me over $250 worth of product to make up for the mistake. Good company, bad product!
In order to properly clean an air box, you need to remove your air filter and clean the whole air box with cleansers and water. Made out of a hard, composite material that completely covers your air intake and won't allow any liquids to penetrate to your intake. The contact point on the air box cover has a strip of soft rubber that creates an impermeable seal. Simply remove your air filter and install your air box cover. Your air box is now ready for cleaning with No-Toil Air Box Cleaner.
