Tri-Spark Power 6-volt Single Lead Coil


  • Universal fitment, perfect for 12-volt, Tri-Spark electronic ignition systems used on twin cylinder British Bikes
  • Can be used as a high-quality, high output, coil on 6-volt systems


  • Oil cooled for maximum efficiency with updated CNC interlocking plastic bobbins (no paper like old Lucas coils)
  • More robust but lighter than epoxy-filled coils.
  • Extra windings using heavier wire and a high grade core for improved spark energy and duration
  • More than double the spark duration of the stock Lucas coil and 55% higher spark intensity than most common competitors
  • Longer spark duration, and higher intensity make these hard to beat
  • Spark duration is desirable for easy starting, especially on cold engines where fuel mixture is the most varied
  • High spark intensity minimizes the chance of a misfire, reduces plug fouling, and can make the most of high compression engines
  • Individually inspected and tested to ensure they meet all specifications
  • 40mm OD can is has the same appearance and dimensions of the Lucas M6 coils
  • Professionally packaged with terminal hardware included
  • The Aluminum can takes well to polishing and will yield a bright chrome like finish with minimal effort.


  • Long duration
  • 3.5 ohms


  • WARNING - These coils discharge with a very high voltage so extra care must be taken to always have a spark plug connected to the HT output.
    A tight fitting rubber cap is required on the coils HT output tower to prevent arcing
  • Never under any circumstances operate the coil without a spark plug connected
