Stay with NGK's or Denso's

+4's are over rated...and if you dont have enough "juice" (MSD or other) its pointless.

Bosch sparkplugs are absolute trash. You should avoid them in the future entirely. Go with NGK's or Densos, your best bet is to use OEM densos. You do not need to get iridiums, just get simple copper core/platinum tip plugs, they shouldn't cost most then $5 a plug.
