I replaced mine last year with Iridium (Denso) and I liked the improvement in idle (smoother) and better (slight) acceleration.

Hi JB. I use the factory spec plugs on my vettes and typically get them from RA very cheap.

Are you trying to solve a runability issue with the car? Or more of a peace of mind/pm type thing?

I’m sure this question has been asked many times.
Does anyone know of a good mechanic that really know C4 vettes in the Toronto area.
