Ok guys I have searched but I noticed alot of the arguement is about gap size.

You can see my mods below: Basically a stage 2 and filter.

Do I need to go with the 1 stage colder plugs or not? Anyone with knowledge or running them please. Also, I live in wisconsin so it is VERY cold out right now..usually about 30 degrees.

Thanks!

 

Usually you go with one stage colder plugs when you throw on a 2.8 pulley. You should be fine right now.

 

Gracias homey! I was asking because cobalt addiction recommends i step colder if running a 3.25 pulley or less and a stage 2 is a 3" so ????

 

i had the dealer put on the 1 step colder ngk plugs when i go my stage 2. and they were gapped at 40. it ran great then. i then put on a 2.8 pully and it ran fine till it got cold out then it started to get spark blow out. then i regaped them to .35. now it runs good again.

 

haha lucky u i had my dealer put them on and the gapped them at .40 and it blew my engine up...and now im stuck with a car i had for 5months made 5payments and now it just sits in my driveway since i cant afford to put it back together

 

Even the stage 3 kit with a smaller pulley doesnt come with colder plugs. Gm tunes them to have stock plugs.

sooooo...we have mixed opinions i see...hmmmmmmm which leaves me where I started.


CONFUSED ON WHAT TO DO.

 

If gm says to run your stock plugs then run your stock plugs. Its not that hard to figure out. If you had a smaller pulley or alot of other mods then you should try out a colder plug. But for now just stay with the stock plugs.
