i have herd that when you turbo your car you should go with a plug that runs colder,,,does this

sound about right????????[sm=smiley20.gif]or[sm=smiley21.gif]

 

yeah, haw many levels or stages colder depends on how much boost

 

im just saying with like stock boost probably around 7 lbs[sm=wootwoot.gif]

 

with forced induction (or even nitrous) colder plugs are a must! depending on the kit you get and boost you are running should determine the spark temp... check with the installer or maker of the kit to see which you should buy. Should run you about $10 per plug.
