Performance Jeeps deserve Jeep performance parts. Whether you are sitting in traffic in your stock Jeep Wrangler 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 Jeep Wrangler 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 Jeep Wrangler radiators are designed and built to handle the rigors of off-roading, severe weather environments, and competitive driving. This Jeep Wrangler radiator is designed to improve heat dissipation significantly, making this an ideal upgrade for a stock or modified V6. The Mishimoto Jeep JK Performance Aluminum Radiator comes with a High Pressure 1.3 Bar Radiator Cap and, as with every aluminum radiator, includes the Mishimoto Lifetime Warranty.
