Using this S&B Cold Air Intake is easy. Just install it following the provided instructions. If you choose the cleanable filter and you mainly drive in the city or on highways, clean it with the S&B Cleaning Kit regularly to keep it performing well. For the dry filter used in dusty areas, blow it out with compressed air to extend its life. When it's worn out, simply dispose of it. Make sure to purchase this product from an authorized dealer to get the Million Mile Warranty. And always use it on the vehicles it's designed for under typical driving conditions.
