Just had the standard massive electrode plugs replaced with fine-wire plugs on my 172 with IO360 on this annual, man what a difference! Why didn't I listen to you guys sooner on that?

like, what difference?

Hey Greg, what kind did you use...Tempest? How much $$$?
what was the most noticeable; easier start, or lower idle, plug fouling?
....maybe too early to tell eh?

I put them in the bottom six holes. Now getting 10F more LOP. I am going to do the top ones too. Champion. No difference noticed anywhere else.
