I am running a B8.5 3.0 with a 034 stage 1 tune. I have not replaced my spark plugs in a long time and wanting to replace. Should I go with stock spark plugs, or ones with reduced gap? From research I cannot find a clear answer. I dont know what the stock gap is supposed to be (.028-.032?) but the NGK BKR9EIX are 0.24 +/- .002.

Has anyone had any experience with this and could help? Thank You.
