4-Volt Lucas Style Ignition Coils
Author: Tri-Spark Date Posted:29 March 2021
We have 4-Volt Ignition Coils Lucas Style back in stock! They can be used with triple cylinder bikes that have a boyer or Lucas Rita wasted spark ignition system fitted. These coils are an excellent upgrade as they wont get too hot.
They are oil filled like our 6-Volt and 12-Volt coils. Oil filled coils have improved heat dissipation and work better than epoxy filled as epoxy is not a great conductor of heat.
The appearance and dimensions are the same as the later Lucas type coil (17m12, 17m6) Diameter 40mm. 1 Ohm Primary.
Both of our ignition systems for the triple cylinder bikes, Classic Triple and Triple Ignition Original Black Box, are sequential firing and not a wasted spark system; that is why they are far superior to anything else on the market. The 4-Volt coils are not compatible with Tri-Spark Ignition systems.
UPDATE JANUARY 2023: The Original Triple Black Box system has been discontinued.
