ngk part # BKR8ES-11

two steps colder than stock, for my gsr....stock block....turbo

I use BKR7ES-11, but that is on a small turbo / lowboost. I think it depends on boost level / HP for how much colder you should go, but I could be wrong. 1 step colder worked well in my car. Hope I helped

How much were the 8's? I run BKR7E's on my turbo B18A running 10psi. They're only $1.68 ea.

I think the coldest you can get a BKR*ES plug in is 7.

I'd go with BKR7ES. 8 series is pretty cold for a daily driven motor.
