About CSF Radiators
CSF has manufactured cooling systems since 1970 and now supplies everything from OEM replacements to the heat exchangers found in professional race paddocks. Their BMW and VAG range is the standard answer to heat-soak on tuned cars.
What makes CSF Radiators different
CSF builds its own cores — B-tube technology, TIG-welded end tanks and drop-in OEM fitment. On a tuned car the result is measurable: consistent intake temps pull after pull, where the stock system gives up.
