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.
The cooler used in this system is a highly efficient, radiator-style, plate-and-fin heat exchanger. In this system, finned chambers provide increased surface area for fluids to spread out while also continuously agitating them, resulting in superior heat transfer with minimum pressure drop.

- PSI Pressure through the Sandwich Adapter and is Flow Lost in Engine Oil Cooler Kit # D15405
- I spoke with my contact at Derale regarding the Engine Oil Cooler Kit, # D15405. He stated that typical pressure through the sandwich adapter on a vehicle at 3,500 RPM is 50 to 60 psi on a normal system and up to 90 on a high flow/high volume system. The adapter itself can easily manage that amount of pressure.
He went on to state that any time a component like this is added to a system there will be some flow loss and oil pressure lost but with this system, it will be a minute loss and it ma

Provided that you are within the range of the hose you should not see any significant change in oil pressure or flow when using this kit.
