Mishimoto 2020+ Toyota Supra GR 3.0L Performance Aluminum Radiator Kit (w/Auxiliary Radiators)

Help your 2020+ Toyota GR Supra 3.0L stay cool with the Mishimoto Performance Aluminum Radiator kit! The latest Supra has taken over the role of being an icon for the tuning community, but even being backed by BMW, high coolant temperatures can still bring your track day or canyon carve to a screeching halt. It's a tag-team effort to keep the A90 Supra cool, and we here at Mishimoto made sure to overhaul both the primary and auxiliary radiators for optimal cooling performance. All three radiators were revised from the ground up, starting with the construction. We ditched the slim stock core and plastic end tanks in favor of a full aluminum, TIG-welded construction, sure to stand up to the abuse from the street, track, or drag strip. The primary radiator features a 1.65" thick core, not only increasing fluid capacity but also the core volume by 31-percent for improved heat dissipation. In addition, the updated tube-and-fin design employed on this radiator also expands the external fin surface area by 57-percent to further improve the transfer of heat. Finally, to ensure a rock-solid core, we also utilized strutted tubes on our primary radiator for a core that resists chassis flex, preventing cracks or leaks in your cooling system. The auxiliary radiators also received a similar treatment and have been revamped with a full aluminum construction. Both cores measure in at 1.57" thick with a 30-percent boost in core volume and 180-percent increase in external fin surface area for maximum cooling properties. All three cores are available in a polished finish and include the Mishimoto Lifetime Warranty for a worry-free installation.

Mishimoto performance radiators are designed and engineered to maximize cooling efficiency, boost engine functions, and, most of all, protect your engine from overheating. Many stock radiators can't handle the additional heat that comes higher horsepower levels. So, swap out your stock radiator for an all-aluminum Mishimoto.

Key features and benefits of Mishimoto performance radiators include:
• Available for universal and exact fit applications (no cutting or modifications required)
• All-aluminum construction for optimal heat dissipation, improved strength, and reliability
• Increased cooling capacity due to their massive core size
• 100 percent brazed aluminum core for minimal distortion, low stress, and clean joints
• Available in various sizes with 2-row or 3-row cores
• TIG-welded for clean, strong welds and increased durability
• Magnetic drain plugs capture metallic debris or fragments
• Included high-pressure 1.3 bar cap raises the coolant boiling point for greater safety and efficiency
• Automatic transmission and accessory coolers included where applicable
