Mishimoto Aluminum Oil Cooler Kit for 07-11 Jeep® Wrangler & Wrangler Unlimited JK with 3.8L Engine

Your high-performance JK demands a cooling solution that can keep up in the most extreme environments. Whether you are cruising through the dunes or hitting the trails, properly regulated oil temperatures are vital to the life of your engine. Excessive temperatures result in rapid oil degradation and can put a quick end to a fun day in your rig. Mishimoto has the perfect solution for controlling oil temperatures – the Jeep JK direct-fit oil cooler kit. This kit utilizes precision-engineered JK-specific mounting brackets, pre-made stainless steel lines, oil filter sandwich plate, and all hardware necessary for a quick and easy installation. The Mishimoto Jeep JK oil cooler kit adds .65 qt to your oil capacity and reduces temperatures by up to 40 degrees while maintaining minimal pressure drop. This kit is a perfect complement to the Mishimoto Jeep JK transmission cooler kit and the Mishimoto all-aluminum radiator for the ultimate cooling solution for your Jeep JK. As with all our products, this kit includes the Mishimoto lifetime warranty.
