Spark Plug Help

ReegDawg707 said

https://www.napaonline.com/en/p/NGO2635currently running Autolite plugs in my ol 65’ Dart 3.7 225. Ran for a day and then took a ****. New carb, new distributior, wires, cap, rotor and plugs. Mechanic thinks it’s crappy plugs. I purchased NGK V-Power and the old dude behind the counter was pretty hesitant and said “it usually requires Autolites” but I said no. Am I okay putting these on? Or will it mess something up? Thank you in advance!

People who get weird over putting an NGK plug in a chrysler... meanwhile recommending a Ford plug... just slowly walk back away from them keeping eye contact till you're safely out of that store.

Resistor or non resistor, after that... run whatever brand you decide to be hung up on.

I'll only give you a couple tips when you make that decision...
1. make sure it's a plug that is finished in such a way that you can easily see the mixture color on the base ring and timing mark on the tang.
2.make sure it's the right heat range.
