Mishimoto 20+ Toyota Supra Aluminum Radiator Kit

The 2020+ Toyota GR Supra is a fantastic car for spirited driving, but even with its BMW-derived engineering, high coolant temperatures can cut your track days or canyon runs short. This Mishimoto Performance Aluminum Radiator kit is designed to tackle that challenge head-on by overhauling both the primary and auxiliary radiators for significantly improved cooling performance. Mishimoto has completely rethought the cooling system, moving away from the stock radiator's slim core and plastic end tanks.

Instead, this kit features a full aluminum construction with TIG-welded end tanks, built to withstand the rigors of street, track, and drag strip use. The primary radiator boasts a 1.65-inch thick core, which not only increases fluid capacity but also boosts the core volume by 31 percent for better heat dissipation. Its updated tube-and-fin design expands the external fin surface area by 57 percent, further enhancing heat transfer. To ensure a robust core that resists chassis flex and prevents leaks, strutted tubes are utilized in the primary radiator.

The auxiliary radiators also receive a full aluminum upgrade. Each auxiliary core measures 1.57 inches thick, offering a 30 percent increase in core volume and a substantial 180 percent increase in external fin surface area for maximum cooling. All three radiator cores are available in a polished finish, and this kit comes with Mishimoto's Lifetime Warranty, offering peace of mind for your installation.
