Using bk8re iridium plugs (no copper ones available) at .030 gap (what they came out the box with) and seem to be working fine so far.

What is the best plug setup to go with for a Stage 2 Cobalt with a 2.9 inch pulley? What are the advantages/disadvantages to a copper or iridium plug?

NGK BKR9E Iridium Plug *Three Ranges Colder*

Denso Iridium IK24 *Two Ranges Colder*
Denso Iridium IK27 *Three Ranges Colder*


Stock Gap is 0.45"
PSi-Fi Pulley Kit Recommendation gap is 0.28"
Intense-Racing GM-MAF-T/42.5lbs Injectors/2.8" Pulley Gap recommendations is 0.45"
South Florida Pulley Headquarters suggested NGK BK7RE gap is 0.35"

For those of you running 2.8" or below. TWO RANGES COLDER IS RECOMMENDED.

The one stage is just not cutting it, well for me atleast here in California.

For those of you that want to go balls to the walls like Jmc007 with the 2.6" Pulley. Do yourself a favor and go with the 3 ranges colder plug.

I personally am a NGK guy, i've had a bad experience with Denso (but I know they are a great plug).

I used the Autolites for like a day and hated them. Car felt like shit..

Anyone with anymore information to add, please do so..

I don't know if you guys know it but their is a copper core 2,3 steps colder than stock,they are racing plugs made by NGK,they are non-resistor plugs,so the radio my be an issue for some but here is the part # R5671A-8 two steps colder and #R5671A-9 three steps,I am using the 2 step colder with a 2.8 pully gapped at 35
