I wanted a high flowing air filter for my 08 HHR SS. I ordered a K&N direct replacement and an aFe Pro Dry Flow universal unit with the correct measurements for my 08 HHR SS. I tried both filters and drove a few miles with each filter installed. I noticed an improvement in throttle response with both filters over the stock paper unit. I decided to use the aFe Pro Dry Flow filter b/c it dose not require oiling after cleaning.
