temporarychicken Posted August 1, 2023 Report Share Posted August 1, 2023 Some brands of oil filter throw a crush washer in, but sometimes you're unlucky and there isn't a crush washer included. You always seem to get the big rubber o-ring that seals the oil filter housing to the engine underside though. 1 Quote Link to comment Share on other sites More sharing options...

½cwt Posted August 2, 2023 Report Share Posted August 2, 2023 Cheaper elsewhere, but for completeness, the Porsche part number is 900 123 106 30. 1 Quote Link to comment Share on other sites More sharing options...
