Whether you are sitting in traffic in your stock Jeep or ripping through the trail in your supercharged JK, a reliable and effective cooling system is a necessity for reducing engine component wear and for increasing engine longevity. The Mishimoto Jeep JK all-aluminum radiator is precision engineered for direct bolt-in fitment that requires no modification to your vehicle. This radiator provides significant increases in efficiency, thanks to its 1.5” thick core and 160% increase in volume over the factory radiator.
The Mishimoto Jeep JK radiator is constructed from high-quality, aircraft-grade aluminum with TIG-welded end tanks and a 100% brazed aluminum core. Our radiators are designed and built to handle the rigors of off-roading, severe weather environments, and competitive driving. This radiator is designed to improve heat dissipation significantly, making this an ideal upgrade for a stock or modified 3.8L. The Mishimoto Jeep JK Performance Aluminum Radiator includes a 1.3 bar radiator cap and the Mishimoto lifetime warranty.
