I'm in Oz, so maybe different options from you. I've ordered from eBay, dealers, and Jack Lilley in the UK.
Interestingly, the last half dozen I received have a different part number, and seem to be slightly shorter, so they fit more easily. I think it actually said "supersedes T1218001" somewhere. Search the interwebs for that part number, and you'll find suppliers, you can usually get them cheaper by buying in bulk.
The original filters are a bit of a tight squeeze, but not so tight you need to worry about bunging up threads or anything. They've protected my engine for 16,000 track km so far with zero issues.
