Description

Toyota GR Supra A90 (20+) / BMW Z4 G29 (19+) Mishimoto aluminium heat exchanger

The Mishimoto heat exchanger Supra replaces the stock heat exchanger of the air-to-water intercooler system in the 2020+ Toyota GR Supra 3.0 and the 2019+ BMW Z4 3.0 (G29). It cools the coolant of the intercooler integrated in the B58 intake manifold, keeping intake air temperatures down.

Toyota and BMW integrated the intercooler directly into the intake manifold, but the stock front heat exchanger remains a weak point. Mishimoto ditched all plastic: end tanks, core and ports are aluminium and TIG-welded. Strutted tubes in the core resist bowing and flexing under hard cornering. The core is larger, with 31 percent more core volume and 48 percent more external fin surface area. With the dual-pass flow and louvered fins, Mishimoto recorded a 5 to 7 °F (approx. 3 to 4 °C) drop in intake air temperatures and a more consistent intercooler coolant temperature.
