Tri-Spark coils have extra windings using heavier wire and a high grade core for improved spark energy and duration.
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.
This coil suits two spark plugs per cylinder installation in combination with the Tri-Spark Classic Twin ignition system.
Primary resistance 1.8 Ohms.
Mounting hole spacing is 90mm. Click here for a dimension drawing of the dual lead coil
Can be used on a 1968 BMW R69 in place of the magneto - still using the standard points and condenser (read our blog article for more information).
