I pulled a spark plug just to check one out, and they haven't been changed in a very long time. They have a monster gap! ~.085" Pretty huge.

I plan to change them all tomorrow evening, and i am guessing

that will make a significant change.

 

Yup, mine looked just the same, but it didn't make as big a difference as you would think. Definitely a step in the right directions though

 

Holy gap
