Thermostatic sandwich plates provide an oil take off from the engine block to supply a feed to oil coolers and other external oil devices. These thermostatic sandwich plates will only circulate oil once it reaches 80 degrees C. This allows the oil to warm up quicker reducing engine wear.
The plate fits between the engine block and the screw on oil filter and has two female ports for feed and return of oil flow.
Sandwich plates are available to suit most cars with a spin on type oil cooler.
