Rabbit Racing oil filter sandwich adapter plate AN10 M20x1.5 with thermostat

This so-called sandwich plate is required to connect an external oil cooler.
In contrast to the normal sandwich panels, this version has a thermostat.
This opens at 75°, so the oil only flows through after the engine has reached operating temperature
routed to the oil cooler.

Installation takes place between the oil filter holder / heat exchanger and oil filter.
