These guys are a small VW shop and parts store (I have no affiliation with them) that just carries the normal Worldpac stuff (no dealer-only items) but they generally quote the lowest retail price I can find anywhere, and they ship quickly. Don't bother with their online quote form, they never seem to reply to it. Just call them up...

The counter guys do have considerable VW engine knowledge, which is pretty unusual for an auto parts store.
