Just a cheap set of Autolites. Don't buy into the hype of trick plugs

Yep, good old Autolite resistor copper cores. They're only like $1.50 each.

Standard autolites are great and are what I run. But I have seen this

I thought about it but I don't think its worth it. I wonder how much they are per a plug.
