Just like the rest of the boosted honda community i run the BKR7e's gapped to .26-.28, change every 5k, or every other oil change. Stock b16@5-11psi, daily driven as well as the track a couple times a year.

Been thinking about changing to the BCR 7's after hearing the Supra community talk so much crap about the BKR's divit.

well most of us run the copper core plugs, better conductivity but short life. but at $2/plug its not a big deal.

BKR7E-11's changed with my oil.
I like the feeling of a fresh plug.
