In my opinion, I would move away from Iridium since you are FI and get a copper plug. At your power level, the #6 heat range plugs would probably be best. NGK TR6 are very popular. (part#4177)
I moved to the ngk br7ef which is a non extended tip copper plug in the #7 heat range, but I dont like the idle/driving manors. Considering going back to the tr6.

The TR6s were definitely one of the options I was considering. Thx! What about gapping them?
