CSF is well known for making the best A9X Supra and BMW G-Series cooling systems on the market. Naturally, they have been most successful with the B58 crowd. With years of feedback from Customers, Race Teams, and Development Partners, CSF has more B58 cooling experience than any other company in the world.

With more and more people pushing the limits of the Supra, the factory radiator has started showing its limitations. Bigger turbos cranking out more power create a lot more heat that needs to be dissipated. Furthermore, the heat exchanger is mounted directly in front of the radiator, so all the heat shed by the charge air system runs over it. In racing applications this can be detrimental to engine coolant temperatures and risk sending your Supra into limp mode. In addition, many of these cars are getting to an age where wear and tear necessitates replacement.  

CSF began development of the Supra radiator over 1 year ago with thorough race testing done by Titan Motorsports and Studio RSR. To give customers the best possible performance, CSF incorporated its latest 5mm fin cooling technology. This new fin technology increases the heat transfer area over a traditional radiator by 20-25%.

CSF vs OEM
The original OE radiator from Toyota/BMW is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, there is always room for improvement. The 4mm fins on the OE radiator made the system fairly efficient for a factory unit. The core itself is one of the biggest limiting factors at only 34mm thick and a single cooling row.

With data collected by development partners and race teams, CSF was able to design the ideal High-Performance replacement. The CSF radiator features the latest 5mm fin technology. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is much larger than the factory featuring 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance.

Real World Testing
CSF understands that this radiator will be used in motorsport competitions. While it would have been easy to engineer a good radiator and call it a day, CSF wanted to make the best possible radiator that would hold up under the most demanding conditions. This requires more development time with a lot more testing, but the result is the ultimate performance radiator you can depend on. CSF worked closely with two R&D Partners to test the radiators in multiple motorsport environments. These initial test units were made using CSF’s 42mm 2-Row core with 6.5mm fins.

Drag & Roll Racing
Titan Motorsports was the perfect partner to test the radiator for drag racing applications. CSF has a long relationship with the team at Titan Motorsports. They have one of the fastest A90 Supras in the world and compete in drag and roll racing competitions across the US. Over the past year, the Supra has been run in countless competitions in some of the hottest and harshest environmental conditions. Over the past year, the radiator has performed very well offering lower engine temps at both idle and during runs.

Great quality at a great price too!
Husband got this for his ‘05 Camry and says it looks and fits just like the original. He was happy that it simply slid in with no adjustments needed. It’s been a couple months now and no problems at all. Very satisfied with this item.

Electrically good. Fitment not so good.
This starter worked fine when installed. The only reason I didn't give it a 5 star rating was fitment. the hole in the bell housing is slightly larger than the starter. The old starter, OEM, was a right fit. This puts all of the strain and torque of starting the engine on the two bolts that hold the starter in. I expect this to fail at some, hopefully, distant point in the car's future. In order to retorque the starter bolts, the battery and airbox have to be removed.
