What’s better than a Wrangler JK that can go anywhere, anytime? A JK that can go anywhere, anytime, with a HEMI under the hood. And even 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.

Of course, reliability is also a major concern for any Wrangler owner. Mishimoto has devoted countless hours of R&D to bring the JK market a stronger, more reliable radiator. Our HEMI conversion radiator features extruded, internally strutted tubes to help combat flex within the core. These strutted tubes provide the radiator with greater rigidity and durability, reducing the potential for cracks and leaks. Just like our other Wrangler JK products, this radiator is a direct fit and accommodates the stock JK radiator fan, A/C condenser, and transmission cooler.

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.
