what spark plug?
what spark plug? what spark plug should I go with when I change my plugs in the next week or so. mods are in my sig. just wanting to know what brand and gap you guys would suggest for best performance.
depending on how you treat your car money spent on iridiums can be well spent....you run it hard alot that copper will burn off really fast....
i went with ac delco iridiums pre-gapped, they went through 3 motor break ins, and over 30k miles...they look brand new when i changed them....so yes they were worth the 50$....copper would not have held up over that
