I never got help on the last one...............

Anytime you want to put some snake jelly on this new one, you are more than welcome to. LOL

If you had touched the other one, I prolly would have got into the 9's. LOL

i realy like the ngk plugs,not sure about the # but i can look.

Check if you don't care, I can try both.

R5671A-8........i run alky.the last #[-8] is the heat range.on gas i'm not sure what you'd want.i've had good luck with them.

Thanks, I'll have to check them out.

That is the same heat range as the AR3924. The autolight plugs will get lower in number as they get colder and the NGK will get higher in numbers as they get colder. I run one heat range colder with alcohol.
