MG201-7 microGreen Oil Filter Cut Open.. Now I made a post how clean the oil seemed to be when i used this filter and just so you know I always do my own oil changes and at the end of my OCI my oil is always dirty.. However with this filter the oil was so clean it could see through the oil as it was draining out the drain pan. Here are pics of the filter cut open.. Now the oil in the filter is very dirty.. check it out. Just for notes.. I can tell you the base plate was very thick and the gasket with probably 3 times as large as normal. The bypass / extra disc filter at the bottom is interesting.
