Is anyone spraying on stock GM plugs? If so how big a shot are you using and what type of results did you see doing it?

 

I have sprayed on them before, not recommended. Change them out to at least TR6's for safety. I used to spray a 100wet shot, but after realizing what a POS those plugs are I switched. Gapped the TR6 top 38 and it was spray heaven!

 

stock GM plugs are platinum, you will melt the tips right off the plugs. I use NGK TR6's in my car.

 

Thanks for the info.
