just got some screamin' demon coil packs and they recommend to gap the spark plugs to .065 inches. I also got some ngk iridium spark plugs. Is there any trick to using the gaping tool? I have never gapped plugs before.

I think all plugs for the mustang are at .065 or if you wanna make sure they are at that..... go to a mechanic shop and ask them to messure them with their tool....... they will tell you were they are at but I got new ones and they were at .065 when they messured them
