Using this product is easy. First, make sure your OEM Swift airbox is clean. Then, attach the rainhood on top of the airbox using the mounting O - ring. If you bought the complete kit, connect the rubber boot to the airbox and secure it with the hose clamp. When it's rainy, the rainhood will do its job of keeping moisture out. Remember, don't use it in extremely harsh weather conditions as it might reduce its effectiveness. For maintenance, clean the rainhood regularly with a mild detergent and water. Let it dry completely before putting it back on the airbox. Store it in a dry place when not in use to prolong its lifespan.
