S1 Air Duct

[chingers]

Looking to replace the flexible air duct between the filter box and the throttle assembly on my S1 (2.8)to prevent the possibility that air leakage may be upsetting fuel metering. Does anyone know if this is a standard Ford part (Sierra/Capri/Granada) or is it a TVR part.
Any input would be gratefully received.
Thanks

Thanks for the suggestions. My fear originally was that the Ford part would be the wrong length and you've confirmed that. I'll be following up on the other suggestions.
Thanks again.
