I got B20B4 motor that's turbo running 10 psi and I was wondering how do I tell if i'm getting a colder plug, I plan on using ngk spark plugs but don't know what type of spark plugs to get, can someone give me the spark plug number for the b20b4? And what should i gap it at?

only in a dyno you should be able to confirm 100% which ones perform good with your set-up.
