6-Volt Dual Lead Ignition Coil

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.

HT leads 60cm long included - Spark plug caps sold separately. Spark Plug Caps, two caps per coil required.

Mounting hole spacing is 90mm.  Click here for a dimension drawing of the dual lead coil

They do not have a negative or positive primary terminal, you can wire them either way.

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).
