Wish I'd have saved the one that came off my Contour, it hadn't been changed since May 2011 (sat most the time until I bought it, barely above 3k on the change) but I wound up throwing it in the dumpster. It was a very greasy, dirty PZ-173, but had the old holy center tube instead of louvers. Kinda makes me wonder what a pre Tearolator era jobber filter was like! Although this one you posted looks great, maybe Purolator is improving! I'll have to save and cut the FL-500S the car has on it now when the time comes..
