| Thanks Beken, thanks DaFlake,
My guess is that I've got an OEM filter too. It certainly didn't look like a cotton type (no wire mesh), although it did look somewhat better than other paper filters I've seem.
My concern was that after reading the service information it seemed that the replacement interval was longer than I would have expected from a normal paper filter and I didn't want to be throwing away a "special" OEM filter that just required cleaning and oiling (a la K&N).
Rather than replace the OEM filter I might splash out on a cold air intake in a little while anyway.
