Using this S&B KF - 1080 intake filter is easy. Just replace your old filter with this new one in your S&B Cold Air Intake Kit. If you choose the cleanable option and drive mostly on city streets and highways, clean it with the S&B Cleaning Kit regularly to keep it working well. For the dry filter, if you drive in dusty areas, use compressed air to blow out the dust to extend its life. When it's worn out, simply dispose of it. Make sure to buy this filter from an authorized dealer to get the Million Mile Warranty. And remember, this filter only fits S&B intakes, not OEM ones.
