I purchased a K&P S38 filter for my 2008 BMW 328xi (N52). Normally the paper filters for my car come with one black and one greenish o-ring for my filer housing cap - are these parts sold individually or does anyone know the exact sizes of the o-rings? https://www.ecstuning.com/b-mann-parts/oil-filter-kit/11427566327~mn/ https://www.ecstuning.com/b-k-and-p...lter-w-machine-finished-end-caps/s38~k-and-p/
I'm just looking for the individual part numbers because they'll eventually wear out. The stainless steel oil filter part just gets cleaned and reused forever.
This shows a # for one o-ring; looks like '08 was a LCI switchover year, you might want to start at the top of realoem.com & put in your vin or use your exact production month. You might have to measure the dimensions to see if you can source them, or query the oil filter manufacturers, maybe that could lead somewhere. http://www.realoem.com/bmw/enUS/showparts?id=PK73-USA-05-2008-E90N-BMW-328xi&diagId=11_3867
K&P ended up giving me the exact details of where they buy the o-rings they include with the stainless steel filter and the dimensions. Both are Buna-N 70D: The larger o-ring is 3.5mm CS x 80mm ID The smaller o-ring is 2.5mm CS x 7mm ID
