      • Kit Has an Oil Cooler, Mounting Brackets and More
      • Cooler Reduces the Oil Temperature
      • Designed for 07-11 Jeep Wrangler JK Models


      Perfect Engine Temperature. The oil cooler in this kit minimizes oil temperatures by up to 40 degrees and maintains minimal pressure drop, enhancing the engine's performance. It lubricates high-wear engine components such as piston rings, skirts and cam bearings to maximize the engine life. This oil cooler maintains a free flowing system which will increase your oil capacity by 0.75 quart to ensure proper oil temperature.

      Additional Information. This oil cooler kit complements the Mishimoto Jeep JK transmission cooler kit and Mishimoto all-aluminum radiator. If you live in an area which reaches subzero temperatures frequently, the Mishimoto Thermostatic oil cool may be a better option (see part number J101048), as it only switches on when oil reaches high temperatures.

      Kit Includes. This kit from Mishimoto contains an oil cooler, precision-engineered JK-specific mounting brackets, pre-made stainless steel lines, oil filter sandwich plate and all necessary hardware.

      Application. This oil cooler kit is designed for 2007-2011 Jeep Wrangler JK models.

        Not having an oil cooler stock in my JK was horrible when beating it off road. I would have to stop multiple times when my "hot oil" light came on and it was a buzz kill. Now I can trail all day long without having an issue. Breeze to install, but quite pricey. Worth it though.

        5 2011 Wrangler Unlimited - Messymarvin Installation Time: Afternoon

        Easy install

        I installed it in my 2011 wrangler withough experiencing any big problems. Prior to stalling it I viewed the video on the mishimoto Web site which gives you a good idea of what to expect. Everything fit well but I needed to drill a separate hole to mount the top of the cooler to the radiator support. Other then that it all went smoothly.

        5 2008 Wrangler - Jeeper Installation Time: Full Day

        Overkill? Sure, but it gets hot in the south.

        As with every Mishimoto part ive owned, the quality is excellent and the finish is close to show quality. We wheel down in the hot south and on top of already hot days, the heat from the abuse on the engine worries me sometimes. This was put on an 08 JK and dropped the average oil temp about 20-30 degrees for running around town and close to 40 when really getting on it offroad. Worth it, depends on how you value your engine, but I feel that the reduced heat and consequential wear is! No install issues, although we did spend a good majority of the day making the install look as clean as we could.

        Mishimoto Oil Cooler Kit review by Robert

        The tutorial provided did not have all tools suggested to instal the cooling kit. This had me running back and forth to the store. If it wasn't for that I would have been faster. Quick tip: I also used ziplock instead of the pin provided on the top mounting bracket because it was more secure. When I used the pin it popped of. The fit was a little rough to get in but its manageable. Overall It gives me the confidence to push my jeep for some fun since the last time my hot oil light when off. It gives it an aggressive concurring look pepping out that front grill. I love it

      I have a 2011 jku with a bolt hood lock would that interfere with the transmission cooler

      • Thank you for your question! This will not interfere with a hood lock system if mounted properly.

      Why don't they have this for 2017 jk like mine I liv in az don't they make stuff to keep my oil or trans cooler mines a manual ther somthing for newer jks

      • Hello, for a manual transmission you will not need a transmission cooler. All of the automatic 12+ JK's come out of the factory with a transmission cooler already installed, as well as an oil cooler for the manual and automatic.
