TRI-SPARK IGNITION COIL 12 VOLT - OIL FILLED 40MM DIAMETER
A Tri-Spark 12 volt, oil filled ignition coil measuring 40mm in diameter.
This is a Tri-Spark ignition coil built for 12 volt electrical systems, oil filled, with a 40mm body diameter. It's a modern replacement coil rather than a factory Triumph or Lucas part, meant to slot in wherever your bike calls for a 12 volt coil of this size.

Oil filled construction is the traditional way to build a coil - the windings sit in oil inside the coil body to help manage heat, same basic idea as the coils that came on these bikes originally. We don't have more detail on file beyond the coil's voltage and diameter, so if you're not sure this size and voltage matches what your bike needs, give us a call before you order.
We carry this under the JRC-17-TS12V number, same part as the 12 Volt Coil listing you may see elsewhere.
