Tri-Spark 4 Volt 4V 40mm Ignition Coil(s) Triumph BSA Lucas-Type PN# TBS-0029


Searching for the hottest spark possible when running a Boyer electronic ignition in your Triumph or BSA triple? Look no further! This 4 volt ignition coil from tri-spark features extra windings, heavier wire construction and a high grade core for improved spark energy and duration versus the original Lucas coils & other aftermarket alternatives. The appearance and dimensions are the same as the later 40mm Lucas coils (17M12, 17M6). This coil is compatible with Triumph T150 T160 Tridents, Triumph x75 Hurricanes & BSA Rocket 3 triples fitted with Boyer electronic ignitions, 3 coils are needed per motorcycle.

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.

We understand electrics for British motorcycles can be daunting, if you have any questions regarding fitment and compatibility feel free to contact us prior to ordering.

Please note: Due the nature of the product, we unfortunately do not accept returns on bearings, service tools or electrical components. Please be confident about your purchase before ordering. If you have questions, please contact us.
