I don’t know but worth contacting the ebay seller in my link above to see if they know of anything suitable? There does appear to be more available in the US. Hadn’t realised the Zetec had one too. I think Ford gave up on plastic around 2007. The inlet tract is good on the Duratec but the sealing is a bit iffy and given that they appear to be made from glass loaded nylon it’s hard to imagine how they would even achieve a precision seal across the operating temp range. No surprise they can feel a bit ‘soggy’ to drive.
