Using this intake replacement filter is easy. First, make sure your truck is turned off and cooled down. Then, remove the old filter from your S&B intake. If you've chosen the cleanable 8 - layer cotton filter, when it gets dirty, use the S&B Cleaning Kit to clean it. Just follow the instructions on the kit. For the dry filter, when it's in a dusty environment, you can use compressed air to blow out the dust and extend its life. When it's completely worn out, simply dispose of it. Remember, this KF - 1085 filter only fits the intake kit with a snap - in lid design. If your intake has a clear lid secured with screws, you need to order the KF - 1063 filter instead. Keep your filter in a cool and dry place when not in use. And since it comes with a Million Mile Warranty from S&B when bought from authorized dealers, enjoy peace of mind during normal driving.
