Ngk B7ES, gap them around .028" and .032" (Use with 5K Ohm resistor cap)
The better plug is the NGK BR7EIX, only gap it once before it is used/heat cycled (use with non resistor cap)
I'd only use a colder plug if you can hear it detonating, mine with a stock heat range plug(7) on 38° C day's here was fine.
