Educate me. 1930 model a spark plugs run from $5 to $45. What is the difference? Worth it? Why?

Fit, finish, heat range, manufacturer, & looks. If they are original NOS they really cost more.

Not worth it in my opinion. Spark is spark from a plug all other things being equal. If you are building for fine point then you need the expensive 3X plugs.

I've never had a problem with the Motorcraft TT10s they're cheap and run well. Never fouled one.
