I'm pretty sure stockers are platinum. Plus I was always told copper is good for boost. Iridium works too they are just a lot more to buy but will last longer as well. I have the bkr7e's in right now on a 2.9" and they seem to be working just fine.

"colder plugs" just means the gap of the plug. i was running the bkr7es with my 2.9 and i was fine. since i switched to 60s and 2.6, im occasionally getting a little knock at 5500 rpms, i just think i should get new plugs (i put about 30k on them so far)

The temperature of the spark plug's firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called "Thermal Performance", and is
determined by the heat range selected.
It's important to remember spark plugs do not create heat, they only remove heat. The spark plug works as a heat exchanger
by pulling unwanted thermal energy away from the combustion chamber, and transferring the heat to the engine's cooling
system. The heat range is defined as a plug's ability to
dissipate heat.
The rate of heat transfer is determined by:
The insulator nose length
Gas volume around the insulator nose
The materials/construction of the center electrode and porcelain insulator

just a little something
After i got stage 2 on my car at like 2k miles, about a week later my stock platinum plugs were fried, i replaced them with some new ones i had laying around my house and a week later they got fried also (car was misfiring hard) I went and bought the ngk bk7re copper plugs, and since 2500 miles im now at almost 16k I have had no problem with the same set of copper plugs.
even if i have to change them once a year (which i dont think i'll have to), it only cost me 8 dollars for 4 plugs which is fine by me.

BTW, your wrong. The stock plugs are platinum.
Since you have iridium plugs, then they shouldn't be going bad. However, I would suggest going 2 steps colder then stock with that 2.6" pulley.

I just picked up some of the bkre7 IX and they are working out great so far, way better than the bkre7 r's I was running. The only thing that I could complain about is, I snapped one of the plugs tips when trying to gap it. So I had to go by another one, later I found out you're not suppose to gap the iridium because the tips are so delicate.
Oh well I gapped them at .35 and everything seem fine.
