Mishimoto 2020+ Toyota Supra Aluminum Auxiliary Radiators

The A90 Supra runs two small auxiliary radiators alongside the main one, and the factory units use a slim core with plastic end tanks. Mishimoto replaces them with all-aluminum radiators that hold more coolant and have far more fin area, which helps keep temperatures in check on a stock or modified car.

What you get

• A pair of auxiliary radiators, left and right.
• Thicker brazed aluminum core, 1.57 in thick, with about 30% more core volume than stock.
• About 180% more external fin area than the factory units.
• TIG-welded aluminum end tanks in place of the plastic ones, with a polished finish.
• Strutted tubes through the core for strength and to reduce the chance of leaks.

Good to know

• Mishimoto says the extra fin area pays off most when paired with their aluminum main radiator.
• Covered by Mishimoto's lifetime limited warranty.
