CSF Toyota Supra (B58) A90 & A91 Auxiliary Radiator Upgrade

CSF has long been known for their direct drop-in cooling components such as radiators, heat exchangers, intercoolers, and more. When considering the A90 Supra their engineers knew they needed to approach things a little differently. In this case the OEM cooling system, the A90 & A91 platform is unique, opting for a pair of auxiliary coolers. For stock cars this system works pretty well, but who likes stock? Enter the CSF Auxiliary Radiator Upgrade. These twin coolers supplement the factory cooling system to provide just the right amount of cooling for high performance and track driving.

The A90 and A91 Chassis Toyotas and BMWs feature plastic rock guards to protect the delicate fins of their OEM auxiliary radiators. Unfortunately, these are designed around the OEM components only. If you put a larger cooler in there that doesn’t line up with the OEM plastic guard you will actually hurt performance. For this reason the engineers at CSF have included replacement rock guards which provide flow in all the right places for these radiators. They also wont block aftermarket aero modifications.

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