Cut open: ST 3506

[labman]

You know, if it hadn't been for the disappearance of the PF 1177 and the hosing I was taking on cartridges for my Ecotec, I likely would never have joined BITOG and would still be doing 3 month OCI's with AC and Pennzoil YB. If you never cut a filter open or look at pictures on the net, holes are of little concern
