Tri-Spark high performance HT coils feature improved spark energy and duration. Oiled filled like the original coils with efficient core materials they have improved heat dissipation and are not susceptible to internal arcing, which is key to producing larger sparks. Vastly superior to the Lucas alternative in build quality and performance.
Connections and dimensions are the same as the later Lucas type coil, 17m12 & 17m6, diameter 40mm.
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.
Recommended for use with Tri-Spark, Rita, Pazon ignitions. 4.5 Ohm primary, 9K secondary
