Description

Toyota GR Supra A90 3.0 (20+) Mishimoto aluminium radiator

The Mishimoto radiator Supra A90 replaces the stock main radiator of the 2020+ Toyota GR Supra 3.0 with the B58 engine. The slim stock core with plastic end tanks makes way for an all-aluminium radiator with TIG-welded end tanks, built for street, track and drag strip.

The brazed core is 42 mm thick, good for 31 percent more core volume than stock, and the updated tube-and-fin design gives 57 percent more fin surface area. It works best together with the Mishimoto auxiliary radiators. Strutted tubes throughout the core make the radiator resistant to chassis flex and reduce the risk of cracks or leaks, even on tuned high-boost B58 engines.
