Here is a mahle OC338 filter cut open, came out of a 2009 Mazda 3 after 6000 miles of use of pennzoil platnium 5w-20. Oil and filter now changed with Valvoline synthetic 5w-20 and another OC338.
Excuse the debris, don't have a proper cutter so had to saw away. I have attached a link to an OEM filter I previously cut open aswell
