  • What Spark Plug is Best

    My 1967 T100R has NGK BR7ES plugs in it. I've been told they are the worst plugs to run. What's your sense?

    Hello John, your 1967 Daytona came from the factory with Champion N3C 14mm 3/4'' reach. I've tried a few different spark manufacturers over the years, but my 1967 Daytona still runs the best with the Champion N3C.

      The N3’s are still available at any auto parts store.
