^^^ Yeah, there were many P1 filters with tears that were posted on here. Purolator has put out a new lineup, but as far as BITOG goes, many members on here who used to use Puro oil filters have moved on to using other filters (like Wix/NAPA, FRAM, Mobil 1, and Hastings/Baldwin).
I know that Mann+Hummel is now over Wix as well, but with NAPA filters being made by Wix, and taking into account the longtime impeccable reputation that Wix has, I believe that Wix/NAPA filters (and all other Wix-made filters) will retain their extremely high quality.
