I have a couple Mitsubishi oil filters from when I worked at the dealer. For some reason, I had one case of these filters come in. Same part number we used all the time, but these filters were different. They are made by Denso, and look totally different. Instead of having a paper like element, this almost looks like it has some foam type filter element. The base plate is thick, you can see the silicone anti-drain back, the gasket is molded and comes pre-lubed. In inside of the canister is not a perforated tube like we are used to seeing, but a plastic frame for the foam type filter. I only have 3 of these left, and have never seen them again. I took some pictures, don't really want to cut it open right now though. Does anyone have any info on this type of filter Thanks!
