I have a new MG101-1 here. I have cut one open before and shown pictures. The louvers are great on the ones I had. The problem is the ADBV doesn't function. No space for it to open. In order for oil to flow it has to push up the whole element onto the large coil spring. When that happens, and it will happen, oil bypasses down the center tube as the ADBV comes off it's seat. Oil will still be filtered some as there is pressure on the medias, but it is a completely defective design. Unless they changed it and someone can show this particular version works properly. I am very happy I didn't put it on my car.
