When cooling matters—and on an E36 it always does—you don’t gamble on entry-level parts. You install what professionals use.

The CSF Performance Radiator for the BMW E36 platform is engineered for drivers who expect factory-level fitment with race-level cooling capacity. This is the radiator we trust and recommend because CSF consistently delivers what many aftermarket brands promise but rarely achieve: measurable thermal efficiency, structural integrity, and long-term reliability.

Unlike mass-market radiators designed to hit a price point, CSF radiators are built around advanced core technology, precision brazing, and strict quality control. The result is a radiator that drops in like OEM—but performs like it belongs on a track car.

This radiator is future-proof. Whether your E36 is stock, lightly modified, or heading toward forced induction or track duty, the CSF design provides the cooling headroom these engines demand—without cutting, bending, or “making it work.”

Why CSF Over Brands Like Mishimoto?

Because cooling isn’t about flashy welds or marketing claims—it’s about thermal efficiency, durability, and consistency under load. CSF radiators are trusted globally in motorsport, OEM supply, and high-performance street applications for one reason: they work when it counts.

Race-proven CSF core technology for superior heat rejection
OEM-style drop-in fitment — truly plug-and-play
Ideal for stock, modified, or track-driven E36 builds
Designed to handle increased power, heat, and sustained load

Bottom Line

This is cooling done right.

Keep your 2020+ Toyota GR Supra 3.0L shifting with the Mishimoto Automatic Transmission cooler. While many enthusiasts might miss the third pedal on the latest Supra’s floor, the quick-thinking ZF 8HP mated with the B58 more than makes up for it. However, even with the latest transmission technology, the age-old enemy to sports cars rears its head: heat.

The tag team at Toyota and BMW were already ahead of the game by fitting the A90 Supra with an external liquid-to-air transmission cooler, but heavy demand can still be too much. With plenty of room to grow, our engineering team expanded the transmission cooler’s core, increasing the volume by 162% and the external fin surface area by 412% while retaining similar fluid pressures within the system. We also incorporated internal cooling fins to maximize cooling power to maintain proper transmission temperatures, perfect for long days at the track or a spirited drive through the backroads.

The Mishimoto Automatic Transmission Cooler for your 2020+ Toyota GR Supra accomplishes all of this with a lightweight, aluminum tube-and-fin core, powder-coated in a sleek silver finish. As with all of our products, this transmission cooler also includes the Mishimoto Lifetime Warranty for a worry-free installation.
