...ooohh my...this is entertaining...but seriously folks. If you don't know what is in one of these things you are suprised to see that all it is is just coiled up paper with lots of tiny holes in it. I know I was surprised when I first saw one. My thought was...geeze...that's it?
My TDI oil filter does not even come in an enclosed canister. The canister is built into the moter and you just take out the old paper filter and a couple of O-rings and replace them all along with the paper filter. That kinda shocked me.
I hear ya.
