Using this filter is easy. Just remove the old filter from your S&B intake and replace it with the new one. For the Cleanable filter, if you drive mostly on city streets and highways, you can use the S&B Cleaning Kit to clean it when it gets dirty. This will help it last a long time. For the Dry filter, if you often drive in dusty areas, use compressed air to blow out the dust and extend its life. When it's completely worn out, just throw it away. Remember, this filter only fits S&B intakes, so don't try to use it with OEM ones.
