Are you bone stock? Any mods impact the desired gap. Stock is .060".

yea get your own gap tool, its like 2 bucks at the counter. ive seen stock plugs gaped upward of .070

How long has the oil been in there and do you know if the car ever had gone low on oil for a long period of time?

hes talking about spark knock. not rod knock.
