yes i have, i swapped the plugs in 1 and 2 after fitting. as you can remove the lead and hear the spark arcing from the lead to the plug tip. when i pull the leads on 1 or 4 when running it makes no difference
i just don't want to get bummed for £150 for a coil from ford as its 'RS unique' so if the part number is the same on the zetec coil then ebay it is.
