I wouldn't be too worried about the label....at least it did not find its way into the internals, but more about what is actually inside some of them aftermarket filters.
Here is what I found inside a PF53 I cut open to see if it could be suitable for my bike.
Don't get me wrong here, I used to like ACDelcos, after all my Dad was a Chevy dealer and I must have installed hundreds of them during my formative youth as a grease monkey, but ACDelco outsourced their filters a few years back and went to a cheap paper cartridge. Here is what the Classic Delco on the left used to look like, I managed to source a couple NOS last year and also cut one open.I even looked at the paper media under magnification over a light table,and....... surprise to me, the OEM Mahle did have quite a few larger "holes" than the classic AC.
I usually stick to the OEMs, but last month I installed a Mobil 1 (M1-102) filter on my bike, that was either that or a long trip to a dealer, but costwise here in Canada they are only a couple bucks cheaper than an OEM. But they do have a good rating on most of the sites specialized in "Oil & Filter Threads".....
Soon I will be cutting that one open too......maybe today if I decide to install my last Classic ACDelco in my bike.
