Cartridge-style oil filter setup...
PRO's:
- Automaker can control almost all of the filter performance. Only function of the filter is the media.
- Filter cost can be cheeeeeap
- Seen some automakers patent the filter design to only fit the OEM housing, so they can up-charge the entire market and make more profits ("pro" for the filter & car makers)
- Cleaner oil changes
- Easier oil changes
CON's:
- The R&D, tooling, and component cost of the aluminum/plastic cartridge-type housing likely far exceeds the low-tech aluminum oil filter mount. Thus the automaker passes along the cost to the buyer in the sticker price.
- With a cartridge, you're stuck with the same center support and bypass valve in the housing. Whereas with a spin-on you get a new housing, bypass valve, gasket, etc every time.
- Up-charge on a patent filter design comes right out of your wallet
- In my opinion, the cartridge filter is more likely to be some made-in-china garbage.
- If you lose/break the cap on your housing, you're screwed.
