Using this product is easy. If you've got the single rain hood, just use the bungee cord to attach it to your airbox. For the complete kit, first install the rubber airbox boot, then connect the airbox hose clamp. Finally, put on the rain hood using the bungee cord. When using, make sure the bungee cord is tightened well to prevent the rain hood from falling off. For maintenance, clean the plastic rain hood regularly with a mild soap and water. Don't use harsh chemicals as they may damage the plastic. Store the product in a cool, dry place when not in use to prolong its lifespan.
