i get my smaller pulley installed on the 28th is it ok to put in colder plugs now? What are the pros and cons?
 


I would wait til you get the smaller pulley and put the plugs in at the same time you install the pulley and then tune immediately after so you don't blow something up
 
With just those 3 your not in need of colder range plugs right now so it would hurt your daily driving more than it would help

The colder plugs is only needed to help offset the extra heat of the blower when you put a smaller pulley on. The smaller pulley moves the rotors faster, which results in more heat, so colder range plugs helps offset that...

I believe this is right? I don't want to misinform...
 
colder plugs burn colder. the hotter the spark, the better the gas burns in the cylinder. you always want to run the hottest plugs you can. however, when you start running more boost you can't run the hotter plugs. predetonation (knock, pinging) is more likely to happen with hotter plugs the more boost you run.
