champion 9Nyc or N9s are a GOOD start! middle of the road, trust me i have been running them for over 35 years

the lower the number the cooler they are with champion plugs

bosch plugs the highter the number the cooler they are

i found it benificial in my motor to run champion N7s two grades lower
as N 9s wer too hot and causing problems, i tried N8s ... not cool enough

so N7 suites MY motor
