Description

Toyota GR Supra A90 3.0 (20+) Mishimoto aluminium radiator kit with auxiliary radiators

The Mishimoto radiator kit Supra A90 replaces all three radiators of the 2020+ Toyota GR Supra 3.0 with the B58 engine: the main radiator and both auxiliary radiators. Cooling the A90 is a team effort, so Mishimoto redesigned all three radiators from the ground up.

The slim stock cores with plastic end tanks make way for all-aluminium radiators with TIG-welded end tanks. The main radiator has a 42 mm core with 31 percent more core volume, 57 percent more fin surface area and strutted tubes against chassis flex. Both auxiliary radiators get 40 mm cores with 30 percent more core volume and a full 180 percent more fin surface area. Together they give the B58 the cooling reserve for street, track and drag strip, stock or tuned.

Installation and delivery

Mishimoto rates installation as medium. All three radiators fit the stock locations. After installation, refill with fresh coolant and bleed the system carefully; with three radiators, thorough bleeding is extra important. The installation guide (in English) is linked below. Lead time: 4 to 7 days.

Three radiators, one goal: keeping the B58 cool under any load.

Why choose this Mishimoto radiator kit Supra A90?

If you push the Supra hard, you get the most from the whole cooling system, not from one radiator. This kit replaces all three plastic-tank radiators at once with aluminium units with substantially more core volume and fin area. Backed by the Mishimoto Lifetime Warranty.
