How about one of these.

Is that the new transgender plug?

I was actually wondering about why I never saw ope autolite plugs. Thats all I run in vehicles for about the past 35 years.

Thanks for sharing this.

If you go to the autolite website and go down to parts lookup they have a pretty good interactive system by make and model including chainsaws and other power equipment.. The 2974 is their equivalent of NGK bpmr7a.
