you got the 071's didnt you The 701's are no longer available from ford, although they are the same spec plug they are supposed to be better than the 071 for some reason, I think I read somewhere that they were the WRC plugs, dont hold me to that though

Regarding the gap, depends what spec engine you have ! I believe the standard gap is 0.8mm but I was advised by stu at msd to gap my plugs to 0.7mm because of my stage 3 head & turbo, something to do with the increased airflow Try pm'ing him, see what he suggests
