Additional Information

As the world leader in BMW performance cooling, CSF has taken the lead in introducing a full-line of competition-grade cooling products and complete packages for the B58 engine (found in the Toyota Supra and many BMW G-Series models).

CSF has already released its most popular Front Mount Heat Exchanger for the B58 Charge-Air Cooling System, highly regarded as the go-to option in the industry to reduce intake air temperatures (IATs) and proven on the world’s fastest Supras.

As more vehicles start to become raced in competitive motorsports, the glaring overheating issues that plague this platform have become even more apparent. CSF has answered the call with the release of new High-Performance Auxiliary (Side) Radiators as well as a world exclusive Dual-Core ZF 8HP Transmission Oil Cooler.

Don’t be fooled by other high-performance aftermarket options that utilize the OEM plastic rock guard. The OEM rock guard’s vertical channel design is specifically designed to only work with the tube spacing found on the OEM core. When the OEM rock guard is installed on an aftermarket radiator, it actually blocks a significant amount of surface area, detrimental to the intended performance. During CSF’s own R&D phase, CSF analyzed both the OEM and other aftermarket offerings and decided to take the extra step, redesigning the included rock guard to allow maximum flow to the radiator core, but still offering ample protection from small rocks and road debris – all proven on CSF’s in-house wind tunnel.

CSF’s new Auxiliary Radiator fits both the left and right side of the vehicle as a drop-in fit, requiring no modifications to install. Featuring CNC machined mounting brackets and OEM style “Quick Connect” inlet/outlet connections for a true plug-and-play installation that does not interfere with aftermarket performance aero modifications.
