According to that handy little thing called the Owners Manual, it should be 0.043" or 1.1mm

I've read that you shouldn't try to gap the NGK iridiums. Can anybody confirm this?

Thats been at times the case..but chk them anyways and the main thing is balance on all 6. Who's to say the box wasnt dropped and closed a gap ???
As a rule, a wider gap will give you a slightly hotter spark----NOT a hotter plug----Apples and Oranges there.
