I know, I know sometimes you're dreaming about Audi R8. Only sometimes though.
Well, now you can have genuine Audi R8 oil cap on D2 -- the best car Audi have manufactured. Ever.

The part will need a very
subtle modification so that the cap sits the right way around. Modification is very easy to do. The eBay seller can send you modified version if you only ask for it. They do it free of charge.
New cap is also better functionally, as is sits a bit tighter. Perhaps only because it is new.
