What spark plugs for boosted SRT10 cars?

What plugs are you guys running for 800-1000 rwhp boosted setups?

I was running the Champion RC12ECC while I was at 650-675 rwhp via Paxton, no problems there. Looking for a colder plug perhaps.

Call Dan at DC Performance. They sell an NGK V grove plug for boosted cars. Can't remember the number though. You should also tighten up the gap some.

The NGK that Dan recomended to me was 4291. Im at 700RWHP on a Paxton. I have also been told to use the Champion RC10ECC.

I did some more digging, found others using the NGK 6987. These are similar to the Champion RC10ECC, basically stock measurements but 1 heat range cooler. I ordered them.

Thanks for the feedback!
