Just my thoughts for what they are worth Andy
Number 2 on David's list says to me .... The word Motorcraft on the leads should be good enough for the IVA inspector.
I belive Motorcraft is an original OEM part & as such, the leads would be surpressed in accordance with the guidelines.
OEM leads have been supressed for years & the makers name should be good enough proof of, type approval.
That said .... If you are in any doubt, change them, not worth paying out for an IVA re-test over a set of leads
