4 leading plug upgrade?
Is there any advantage in running four leading plugs on a modded NA (full exhaust, intake, pulleys and flywheel)? I'm doing the annual tune up in a week or so and if there is any worthwhile advantage I'll order 4 leading plugs instead.
I know RETed and Aaron know this hehe

first of all when people run all 4, they run trailings. not 4 leadings. it probably won't do anything on your N/A. it's mostly a safty thing for moded turbo II's.

Yeah, run all 9's, which are trailings.  Try it and keep pulling the plugs every weekend - if they stay "clean", run them from now on.  The 9's will last longer in the leadings.
