12-Volt Single Lead Hi-Output Coil - Tri-Spark

Tri-Spark Power 12-volt Single Lead Coil

Fits:

• Universal fitment, perfect for 12-volt electronic ignition systems used on single cylinder engines
  

Features:

• 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 M12 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.

Specifications:

• Long duration
• 3.5 ohms

Note:

• 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
• A single 12-volt coil is not suitable for use on Triumph twins. Use two MAP4691 6-volt coils
