got mine right before winter and two of them were somewhere to the tune of .041 compared to other at .035 i believe well the story was that the previous own thought they were "pre-gapped" but little did he know it was way off which made my car detonate a ton... soo after taking them out and getting new ones i noticed one of the plugs was at .047 which just made me frown.... sooo take the 5 mins and gap good to save the motor! : ) happy hunting
