Can anyone help me out? I'm trying to figure out which of the (2) M20 ports is the outlet to the oil cooler and which is the inlet. I'm also installing a AEM oil temperature sensor and need to know which smaller (2) 1/8 inch ports to connect to. I don't want to monitor cooled oil from the oil cooler if that makes sense. Any help is greatly appreciated!

 

oil flows out of the filter in the center hole. So by the left pic it would be the left port.

 

Ok cool, thanks. I figured as much. I've been scratching my head over this for an our or so and Mishimoto doesn't specify in their instructions.
