I have recently purchased a 2006 Cobalt SS with the 2.4 and would like to know if different plugs and wires would really make much of a performance difference. I want to do a cold air induction when they become available but for now, is it worth the money and if so...what brand to use.

 

factory plugs and wires are good until you do a lot more mods. sparking system is pretty good on our cars. go with intake and exhaust first

 

also there are already a few intakes out just incase you didnt know

 

our car doesn't have spark plug wires it has coil overs like the LS1

 

The LS1 does have wires, and its called coil on plug.

 

Would the ss/sc's plugs work ? They are NGK Iridium plugs. Pretty much will last forever. Copper plugs don't last as long but will provide colder ranges. Best for smaller pulleys to avoid retards ! Oh I mean Knock Retard

 

the plugs on the ss/sc are different

the 2.4 uses the same platninum plugs the 2.2 uses

 

iridium spark plugs work better on a forced induction vehicle. stick with the factory ones they are good. go with a intake and exhaust major diff in performance.
