Classic cars have been incredibly important to the enthusiast community for decades. For almost as long as there have been gearheads, there have been older gearheads looking to hold onto a part of their youth. That nostalgic feeling we get from owning or seeing something from our youth is a huge serotonin spike. Those warm fuzzy feelings just don’t stir within us when we see newer cars. Now that the generation of car enthusiasts that grew up loving 80’s and 90’s Audi models are starting to restore and update these often overlooked classics, CSF is here to help. CSF works closely with some of the biggest players in the industry. People such as Ken Block, Brian Scotto (Founder & CEO of Hoonigan), Jason Whipple (Founder of Rotiform), and Diego Azevedo (Owner of AMS Autowerks) are all avid classic Audi fans. Through discussions about projects and builds they were working on, it came to CSF’s attention that there were no high quality performance radiators for many classic Audi 5-Cylinder models. Cars such as the B2, B3, B4, and Quattro. On top of that, the OEM is no longer available for the most sought after and highly desirable B4 S2/RS2. If you own one of these vehicles, you know the only real options for radiators are the hard to find OEM, budget quality aftermarket replicas, or poorly designed aluminum models, until now.
