I'll be upgrading my car to Stage 2 soon and I want to replace the spark plugs while I'm taking things apart. Is it fine to run colder plugs in the car with Stage 2(Or maybe a custom tune)? Would anyone recommend it? I figure it can't hurt anything, but if I'm wrong let me know.

its best that you do run colder plugs

 

just one step colder plugs

 

yea maybe ill try them as well.

 

Yeah, I was planning on just one step colder. I didn't want to douse that kid's zzp post, but I don't really care for them much. Anyone else have any opinions or information?

 

yes you might want to run NGK BKR7E's, or you might just try the search button for this because there is alot of threads on this dating way back
