      Rock auto has excellent prices on plugs, that is where I purchased my NGKs for my 73 and 67.
      One comment, many recommended the NGK plugs over the Champion. Everything is a matter of preference certainly but I noticed no difference between the two. Yes I would get the NGK plugs again but as far as I can see, nothing wrong with Champions as well. My 2 cents.

      I ordered Mopar wires from Chrysler, dealer item. Cap from NAPA, they have the correct color (tan).
      Summit Racing or Jegs as well.

      I used Bosch platinum no tip for 15 years ran great switched to NGK for a few years until I found a NOS set of Mopar Champion in the boxes, they work great the car has good power. The plugs are well plated on the outside too.

      As I said before, many recommended the NGKs over the Champions and when asked why, some replied that the Champion plugs now came from China or Japan. Where do you think NGKs come from? Japan!
      I have had fairly good luck over the years finding NOS Champion plugs at flea markets at car shows. Know what you need before you look and buy as many as you can if they have them.
      The original Service Manual calls for N13Y for 318 2bbl.
