Brand: Setrab Oil Coolers
Setrab sandwich plates have M22 female ports to accept any Setrab M22 O-Ring Port Adapter Fittings (sold separately). This cast aluminum plate has a 3/4"x16 filter thread and a 2 1/2 inch O-ring diameter. This version has no thermostat, so all of the oil can flow unimpeded through the cooler.  
The thickness of the plate is 1 inch so be sure to check for filter clearance.
