K&N Engineering has revamped its Power Kleen High Performance Cleaner and Degreaser (part 99-0621). The spray was originally used to remove contaminants, road grime and grease from cotton air filters. It’s now formulated to clean both filters and most surfaces, including painted surfaces, chrome and plastic. Suggested retail is $12.95.
