*CSF WORLD EXCLUSIVE
Adjustment of Mirror Polished Finish Due to health concerns for our employees, increasing government restrictions in regards to social distancing of employees within our manufacturing facility, as well as an unfortunate break-out of Covid-19 within our polishing center, CSF has adjusted the finish of some of its radiators from our mirror-polished finish to our high-luster satin finish. Same great quality, same great performance, same great customer support
