Need spark plugs for my 2.0 supercharged cobalt with injen intake. What's the best plugs for the car.

 

Just get the one step colder plugs to be safe, they're like 10 bucks from ottp

 

Ya I'm gunna get colder plugs but I'm talkin brand wise witch brand of plugs are good for the cobalt ss/sc.

 

i got NGK plugs, they're nice.

 

They're about 1.80/each from your local auto parts store. 1 step colder are 4644 - BKR7E.

 

Why not just buy new stock plugs?

 

BKR7E, /thread, buy 3 sets. 10 bucks for 4.

 

They replaced them with the 4644

I don't understand why you want one range colder plugs if your only performance mod is an intake. stock heat range plugs would be fine.

 

4644 is the part number (what you'd ask for at the store), BKR7E is the model number.

Agreed. Unless you have a pulley on it don't bother with the one stage colder plugs. You'd be better off with BKR6Es (stock heat range) - number is 6962.

 

Same difference I guess. I thought 4644 replaced the BKR7E as the part number.

Nah, I think it was just changed from some other number to 4644. You can find the plugs by the 4 digit or the part code, either one works.

Don't buy em from Amazon, you can get em all day long at Autozone for like 1.70 apiece (just call ahead as they may have to get em from another store).

 

/\ Those are comparable to the stock plugs right?

 

edit...

 

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

 

let the guy buy what he wants if he doesnt want stock plugs
let him buy NGK's
