The stacked-plate heat exchanger included is the most effective type of oil cooler, primarily because of its increased surface area. Allowing fluid to spread out over this larger surface area decreases the time required for heat transfer to take place, resulting in ultimate efficiency.
The sandwich adapter in this kit provides the external oil lines necessary to install a cooler without requiring you to move the factory spin-on oil filter, making it even easier to extend the life of your vehicle's engine. In addition, the thermostatic bypass feature allows oil cooler than 180 degrees to bypass the heat exchanger, so your engine will warm up faster.
