The Ultimate Cooling Upgrade

The 2020+ Toyota GR Supra (A90) has become one of the most exciting platforms for tuners in recent years. With its BMW-derived B58 engine, sharp chassis, and endless aftermarket support, the Supra is built to make serious power. But as any enthusiast knows, once you start tuning or upgrading turbos, heat quickly becomes the enemy.

That’s where the CSF High-Performance Heat Exchanger comes in. Engineered with the largest core on the market and packed with exclusive technology, this plug-and-play unit ensures your Supra stays cool, consistent, and safe—even under extreme boost and track conditions.

The Problem with the Stock Heat Exchanger

Toyota and BMW designed the Supra’s cooling system for stock power levels, not the demands of tuned or track-driven builds.

• Thin Core: The OEM heat exchanger uses a 25mm, 1-row core.

• Heat Soak Issues: During spirited driving or high boost, charge air temps climb, causing power loss.

• Limp Mode Risks: Excessive heat forces the ECU to protect the engine by pulling timing or reducing boost.

• Bottleneck for Tuners: Once you add upgraded turbos, tunes, or fueling, the stock setup can’t keep up.

For enthusiasts pushing past factory power, a better heat exchanger isn’t just nice to have—it’s essential.

CSF’s Solution: The World’s Largest B58 Heat Exchanger

CSF designed their High-Performance Heat Exchanger to directly address the Supra’s biggest cooling limitations.

Why Cooling Matters for the B58

The B58 is one of the most capable turbocharged inline-six engines on the market. Stock, it’s impressive. Tuned, it becomes a monster. But power always comes with heat.

Without proper cooling:

• Heat soak kills power.

• Knock resistance drops, limiting safe boost levels.

• Transmission temps rise, risking long-term reliability.

With the CSF exchanger:

• Charge air temps stay consistent, preventing heat soak.

• You unlock more reliable horsepower under boost.

• Transmission cooling remains intact for peace of mind.

This upgrade ensures you can run your Supra harder and longer without sacrificing safety or performance.
