A long shot I know, but if any one has a new set of GM FLR8DCU+ 9, (4electrode)plugs, that you are about to fit to your car could you please check the gap and let me know what it is, I ask as I have just taken a set out of my VEC and although they had an easy 12,000 miles, the gap was huge, and am puzzled as to why such a big gap,, thanks ANT.
