wow... u guys dont drive ur cars much!
Im about to hit 37k miles on my G.. Im already over the 4k mark for this year...
So not to get off topic but if im running the step 1 colder plugs n been boosted for about 3-4k miles when should I swap out the plugs for another set of fresh ones?

 

Yeah…I put 15k on my car per year…I need a daily…

^ and in for answer as well…

 

like someon else stated, 6-10k. So annually is probably a good estimate.

I'm in grad school. I live 1 mile from school and i'm there 12-14hrs a day 6 days a week. I dont take my car on long trips and i don't go anywhere around here except school so no reason to drive my car 1 mile to school. More startup wear and tear than needed.
