Easy to use.,
This review is from: K and N 99-5000 Filter Care Service Kit Aerosol (Automotive)
Simple easy to use service kit for any K N filter.
After you clean the filter with the cleaner , it needs to dry completely before applying the spray oil , so you'll need a spare ( or an old ) air filter for a day if you need to use the vehicle while it drys.
