At what point in modding does the cobalt ss/sc's plugs need to be made steps colder?

 

I don't see why it would be bad for you to do with your setup

 

When you go with smaller pulleys because they generate more heat. I wouldn't hurt to get colder plugs with your set up but you wouldn't have to.

 

i copied this from cobalt performance parts.


Stock Pulley Size is 3.346"

Stock System can handle the 3.30"
