Why upgrade

A Mishimoto performance aluminum radiator is the ideal upgrade to the stock Toyota Supra radiator. Designed and engineered to maximize cooling efficiency, boost engine functions, and most importantly protect your car from overheating. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.

Features

• Two-row, 2.2-inch thick efficient brazed aluminum core provides increased fluid capacity and optimal heat dissipation — built for the 3.0L Supra's demands on the street and track.
• Full aluminum construction with TIG-welded end tanks delivers improved temperature reduction for both turbo and non-turbo MKIII Supra builds.
• 1.3 bar high-pressure radiator cap and Magnetic Drain Plug included — raises the coolant boiling point and captures harmful debris, complete out of the box.
