so what is sttock gap? and what should someone w/ stock turbo turned yup to 22 psi use?

 

if using the stock plugs they are iridum plugs and are preset gaps, due to the iridum plugs you can not change the gap setting or you could damage the iridum coating/ plating. this would lessen the life of the plug

 

what if you use copper plug

 

I used stock plugs, stock gap at 26psi daily. No issues.
