Review on 💥 1-Pack Champion Copper Plus 429 Spark Plug by William Auditore

I bought these Champion 3X spark plugs for a 1930 Ford Model A. I used old Champion C-16-C forks that I bought years ago. When I found these plugs available from Revain Prime for less than $17 each, I decided to order a kit. The engine now idles smoothly at even lower revs than with C-16-C plugs. As a previous reviewer mentioned, I don't know if there will be a difference in fuel economy, but I've also heard some say that 3X plugs can increase mileage. It seems to me that these plugs just make a good thing better. See you on the street!
