Anyone have any feedback on some spark plugs. I wanna know whats the best. Thanks
Autolite 104s.
Alright, so i just went out and purchased some 104's, but when i pulled one of them i realized im already running 103's. I only run about 12psi od boost and it runs a 14.2 1/4. do you think i should swap for the 104's?
my boost gauge, in winter holds about 12 and spikes aout 15, in summer hols aout 8 and spikes 12. I know theres atleast 10,000 miles on the 103's.
