I'm using a paper filter from Purolator, model AF-3389, that replaces the stock filter perfectly. I don't know where they came from, how much they cost, or whether they are still available but...
Since I have two left and only replace the filter annually, the answers to these questions haven't been a priority for me. Oh, BTW, the fitment info on the box says BMW Motorcycles K-100 models.
