Mishimoto 20+ Toyota GR Supra 3.0L / 19+ BMW Z4 3.0L Performance Heat Exchanger

If you're looking to keep your 2020+ Toyota GR Supra 3.0L or 2019+ BMW Z4 3.0L running cooler under boost, this Mishimoto Performance Heat Exchanger is a solid option. These cars use an air-to-water intercooling system, which is a smart setup for managing heat, but the factory heat exchanger can become a bottleneck, especially when you're pushing the engine hard. Mishimoto developed this unit specifically to address those limitations, helping to maintain optimal intake air temperatures.

This heat exchanger offers a notable improvement over the stock unit, with a 31-percent increase in core volume. This larger core allows for more efficient heat dissipation, which can result in a 5-7 degree Fahrenheit drop in intake air temperatures compared to the factory part. Mishimoto also includes a galvanized steel stone guard to help protect the delicate fins from road debris, a practical touch that adds to the longevity of the component. The direct-fit design means it's made to install without major modifications, integrating smoothly into the existing cooling system.

Keeping intake air temperatures down is crucial for consistent power output, especially in performance vehicles like the GR Supra and Z4. This Mishimoto heat exchanger is a well-built upgrade that directly targets a common weak point in the factory cooling system. It's designed to work with the B58 engine's integrated intercooler setup, helping to ensure your engine can perform at its best, whether you're on the track or just enjoying spirited driving.
