I have an old Colourtune kit with the 14mm adapter, but this appears too small for the zetec. What size is required and are they available?

Thanks

I got the adaptors direct from Gunson's. Can't remember how much - but cheap.

Hi Bob.

I don't suppose you know the plug size for the zetec? I looked up gunsons and the have 10mm, 12mm, 14mm or 18mm adapters, but I think that is too big. Mine is 14mm and is too small, was thinking it is possibly 16mm?

look up the spark plug number on the web and you should be able to find the thread size
