Default 2008 Mustang gt 12mm spark plug gap for roush S/C
I'm pretty sure I read somewhere that the 12 mm spark plugs need to be gapped to .30 for this application(there are no colder spark plugs available for the 12mm I believe). I can't remember where I saw this. Does anyone know if this is correct??

My girlfriend calls it a waste of money, but I see it as saving money(and time away from her) if I install it myself
