.060 plug gap

[Whitetail15]

my manual for 6.0 liter says .060 spark plug gap. the oem plugs i took out are at .045 and the new ones came at .045

.060 is so wide the tip is at an angle when bent that far.

when you look up specs for an 05 06 chev corvettte (zr6 motor) they say .045.

when is everybody using. i set them at .060 and put them it.

i now read that if you change gap of these plugs, it ruins them. true or false?

There should be a decal on the engine with the tune up information on it. go by what it says.

.060 is fine you'll get a little better fuel ecconomy if you do. There isn't an issue regapping the plug unless they are platnum tipped plugs then you have to use the right tools to gap them so that you do not break the platnum pads off. Most platnum plugs are pre-gapped for the application but they miss a couple now and then.
