Evening, I have a question as far spark plugs are concerned: I'm daily driving my 2g GS-T, and I only just started getting into drag racing at the strip recently, I would start experiencing break up past 6k rpms. Now, I'm running on stock boost levels with bastard 20g but want to eventually turn it up at some point.

- From what I gathered so far, copper bpr7es seem to be the best plugs for our cars, but are they still good for daily driving and the strip?
- What would be the recommended gaps for what I'm currently running?
- What would be recommended for 25 psi on a bastard 20g? (20g compressor wheel and td06 20g compressor cover from Turbolab of America)

Bpr7es with a .20 gap. The driveability aspect is to just regularly change the plugs for the sound mind. Depending on power level of course.
