Need some spark plugs for my 07 cobalt ss 2.0 supercharged with injen intake what type and brand of spark plugs should I get and how much colder.

 

one step colder, NGK

 

dont get one step colder if you just have an intake just get stock

 

Did you even bother reading the responses we posted in the thread you made yesterday about the exact same topic?

Yes I just want to see diffrent people think. Some say colder and some say go stock so I'm still undicitied but more people have said go colder do that might be the route I take still don't know yet.

 

Those who are saying 1 stage colder have no idea what they're talking about. The reason you get colder plugs is to compensate for the extra heat generated by your supercharger when you drop pulley sizes.

Trust me, get the normal heat range. There's no reason to drop down one since you're not running any extra boost.

Awesome thanks for that info. Now does it matter what brand Or any brand will work. And how good are e3 for the colbat people told me there a perrty good plug.

 

NGKs have had the best reviews from everyone who's tried em. They also have the benefit of being really cheap and easy to find.

NGK (6962) BKR6E - comparable to stock plug. Best for stock boost applications.
NGK (4644) BKR7E - 1 step colder (~3" pulley)

You'll want the 6962s. You can order them from Autozone (or whatever your local auto parts store is).
