Sometimes I will cruise to the local mopar dealership to look at the new cars and while I am there I p/u a couple oil filters. I usually get Mopar MO-409 04105409AC from the parts department for my '85 GLH Turbo and '90 LeBaron VNT. This time, when I asked for oil filters for my cars, I got the Magneti Marelli filter part # AML-004 1AML00004A. When I open the boxes at home I discovered a slightly shorter and lighter filter, and the mounting flange is flat and not convex like I am used too. Any expert advice on these new Magneti Marelli oil filters?
