i've posted this already but i need to know if i'm running @5psi on a zc motor
with msd ignition do i need to open the sparkplug gap to something bigger than .030-.032 i will be increasing the psi to 8 after fuel pump and injectors this weekend
but i've heard different things some people say gap the plugs at .030-.032 someone said increase the plug gap to around stock with msd......someone told me to change the gap with boost increase....can someone please help me out here

 

Use the stock plugs, but bring the gap to about 35, that lower gap will shorten plug life with the much hotter msd ignition

 

ive never heard of anyone saying to make the gap smaller....only make it bigger. I used to gap the plugs but I didnt find any difference and stopped doing it. I think I used to gap it to like 40 something.

DOnt they come stock at .044?? The ones everyone suggested to get did....so do I need to make the gap smaller??
