The A90/91 Toyota Supra is no doubt the hottest tuner car currently – both in terms of popularity in the performance aftermarket industry, as well as the amount of heat the car generates with increased power or when being pushed hard on the track or dragstrip.

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 Transmission Oil Cooler.

Our full suite of high-performance coolers can now also be purchased as a complete package to solve cooling issues no matter the environment, and more importantly, help racers stay on the track longer and compete at higher levels, without cool-down laps or falling into “limp-mode.”

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.

High-Performance Transmission Oil Cooler (CSF #8183)

CSF is the world leader in cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies.

An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions – from road racing to the drag strip.

During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use.

CSF has the answer with our industry-leading transmission cooler for A90/91 Supra and BMW G-Series. Installed in the world’s fastest A90 Supra  – Titan Motorsports Drag Race Supra (first and only Supra to reach the 8s in the 1/4 mile).
