Sorry, the genuine Subaru part we used to stock is obsolete. We’re working on an aftermarket version – if the tooling works as hoped, it’ll be much better than any Subaru version.
Subaru used many variants of the flywheel cover. Some have large slots in them or removable sections which seem to serve no purpose at all (if you know what they’re for, please et us know – we’d never seen any use for them). This is the neatest one when used in VW applications.
