Mishimoto engineers started with designing a heat exchanger from the ground up, to provide the largest oil cooler they have to offer and mounted directly to the front of the vehicle for optimal airflow. From there, they also developed an application-specific mounting bracket that also serves as a diversion panel to further improve the airflow through the cooler. The Mishimoto kit also includes a set of direct fit stainless-steel braided lines for a secure conduit to and from the cooler completed with -10AN fittings for a simplified installation.

This Kit Includes:
- One (1) Application-Specific Mounting Bracket / Air Diversion Shield
- One (1) Bar and Plate Silver Oil Cooler
- One (1) 2ft 3in Stainless Steel Braided Hose w/ -10AN Fittings
- One (1) 4ft 8in Stainless Steel Braided Hose w/ -10AN Fittings
- One (1) M22 Thermostatic Sandwich Plate
- One (1) Application-Specific, M22 x 1.5 extended length center bolt

Tech Tip: Mishimoto recommends that you check all thermostat plugs, NPT plugs, line fittings, and other connections to assure they are fully tightened before operating the vehicle. Also, they suggest to check all connections at regular intervals, especially during the first few miles after installation.

Additional Notes:
- Installation will require the removal of the stock coolant-based oil cooler and active grille shutters. Removal of the active grille shutters without tuning changes (NOT Included) may cause a check engine light.
