2G Which spark plugs should I use>

[Deleted member 158854]

I heard a lot about BPR7ES, BPR6ES, NGK Website saids BPR6IX, Im very confusing. These are my DSM mods: Greddy BOV, 3" Catback,Cat-Delete, 8.5MM MSD WIRES, Injen Air Intake, Manual Boost Controller 12 psi, Stock t25 and stock IC . In the next few months I will reflash my ECU and set it up to 15 PSI. What Spark Plugs should I use? and why?

Just use the stock plugs bro, ngk bpr6es. No need for anything else with a t25. . Only need to go a step colder when your around 18-20psi then go to bpr7es.

He got it right... i use 8s in my car in the summer at 24 peak spike boost. I had one of the 7s blow up in the 110 heat but 7s do most people just fine once they get into big boy boost.
