The AFE 90-50001
Air Filter Restore Kit is designed for cleaning the Blue AFE Pro 5R media air filters. Included is an aerosol bottle of AFE blue filter oil
and a spray bottle of AFE filter cleaner. AFE filter oil is highly
refined and helps capture the smallest debris. Recommended re-oiling
every 20-30k miles.
No difference other than the dye in the oil. (AFE does this so a customer can differentiate between the two filters and know the filter they currently have.)
