Ryco is getting filters from all over the place these days and not just China. The last filter I got was for a Mazda and it was made in South Africa.
I wonder who makes the filters for Holden these days? The small filter that they use on the old inline six is the same as one on the Mini. (not the big Z30, it is the same thread as the Z30 but a much smaller can)

I am wondering if someone should knock up an adaptor to go in place of the filter head so that you could fit a remote filter using a Z9 sized filter mounted on the inner guard or similar.

Thanks gents, got the usual present for Xmas, sox and jox, and a $200 Supercrap gift voucher, so I will be taking a cut lunch and going to the post Xmas sale on Boxing day and will keep a look out for one of those now I know what I am looking for.
