FAQ's

  • Question
    What spark plug gap should I use when using the ACCEL HEI coil?
    Answer
    .045 is a good starting point. Check your plugs after 100 miles of driving. The white porcelain around the electrode of a properly gapped plug should have khaki tan coloration. If the plugs look black, close the gap by .005 to .040. If the porcelain is white, open the gap by .005 to .050 to cool the operating temperature of the plug.

  • Question
    What is the difference between coils #8140 and #8145 and should I use a ballast resistor?
    Answer
    The 8140 has 1.4 OHMs primary resistance and will need a ballast resistor when used with a point style distributor. The 8145 has 0.7 OHMs primary resistance and will require a ballast resistor when used with a Unilite or MBI distributor.
