OVERVIEW
The Mishimoto Performance Aluminum Radiator is a direct-fit upgrade for the 2020+ Toyota GR Supra 3.0L. The A90 has become a tuning-community icon, but even with BMW engineering behind it, high coolant temperatures can end a track day or a hard canyon run early.
Mishimoto replaces the slim factory core and plastic end tanks with full aluminum, TIG-welded construction. Core thickness grows to 1.65", lifting core volume 31% over stock, and an updated tube-and-fin design expands external fin surface area by 57%. Strutted tubes run throughout the core for stability, sharply reducing the risk of cracks or leaks in service.
The radiator is supplied in a polished finish and carries the Mishimoto Lifetime Warranty. Mishimoto notes that maximum heat dissipation is achieved when it is run alongside the Mishimoto Performance Auxiliary Radiators.
