Big Rocks, Big Blocks, Big Cooling

What's better than a JK with a HEMI under the hood is a JK with a cool HEMI under the hood. That’s why we’ve developed a performance aluminum radiator for your HEMI-swapped 2007–2018 Jeep Wrangler JK. This radiator includes all the benefits of our direct-fit JK aluminum performance radiator, including an 18% greater core volume, fin surface area, and external tube area, and a 13% increase in coolant capacity over the stock radiator. For even more cooling, this radiator utilizes a dual-pass design to keep coolant in the radiator longer. As with all our products, this 2007–2018 Jeep Wrangler JK HEMI Conversion Performance Aluminum Radiator is backed by Mishimoto’s Lifetime Warranty for unparalleled peace of mind.
