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.

 

anyone? anyone? bueller? bueller? 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.

 

yea, I had a feeling thats the way it works...thought I'd ask anyway. Thanks!!

 

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