"PPL" = Pep Boys ProLine. ProLIne is Pep Boys house brand and oil filters by that name are made for the chain by Purolator.quote:

As to pgtr's worry that the entire end diameter of filter paper pleats isn't sealed, it doesn't have to be. As long as the filter paper ends are at least sealed to the center tube and end cap where they all join, and the edges of the single sheet of pleated media are clinched and sealed to each other, no filterable nasties are going to make it into the center tube and through the outflow port into the engine. Fram's much maligned paper endcaps are only joined by adhesive/sealant to the entire diameter of the filter media pleats as a means to achieve mechanical strength from the pleats themselves as a buckling preventative.
(I've often wondered, if stiff cardstock paper endcaps are so terrible, why is soft paper filtering media alright? And flimsy toilet paper filtering media, too? Oh well, I guess I'm just stupid...)
