Questions on JoyFast High Spark Ignition Coils

  • From Tommy at 8/4/2019 1:35 AM
    • Hello,
      Are the JoyFast High Spark Coils as effective as the R-Magic Power Coils?
      Is there a reduction in fuel economy to achieve the power gains?
      Do the JoyFast Coils prevent misfire and knocking as well?
    • Hello,

      The JoyFast & R-Magic items are different products, have not been tested neck to neck yet.

      JoyFast says that there is no reduction in fuel economy (customers claim it's actually slightly better).

      It should help prevent knock/misfire, but they cannot tell it firmly because it is being controlled all by ECU.
