K&N 69-4515TS PERFORMANCE AIR INTAKE SYSTEM+Air Filter Cleaning Kit for Chevy Cobalt. In use for at least 20,000 miles before going back to OEM. Was installed by previous owner and is now not needed. Cannot say how long was installed before acquired the car. Cleaned filter before listing/packing and wiped off rest of equipment. 7 out of 8 clamps, not sure what happened to one. Also including the Recharge Kit by K&N, their Air Filter Cleaning Kit!!
It has instruction sheet on how to clean filter, real simple. Hit me up if any questions, happy to answer.
