Excellent replacement for both Gill and PVL twin outlet coils. These look cosmetically a copy of the PVL ignition coil to fit 1000 Daytona, 1200 Daytona, 1200 Trophy (For 1200 Trophy models after vin 45788, it is better to use only the Gill coil product code Z128), Bonneville 800/865 (carburettor), T100 (carburettor) and Thruxton (carburettor). There is just one ignition coil used on the Bonneville models, which have two plug lead outlets. The original push fit plug leads also fit the replacement coils. After pulling back the rubber plug lead boot on the coil outlets, just pull the lead out of the original coil and push into the replacement coil.
