Ignition coils

IGNITION COILS

Ignition is ensured by means of two spark plugs per cylinder. The spark plugs are asymmetric and their sizes are different. This is a lost spark static distribution system in which four coils each power the spark plug of the cylinder located underneath it and that of the cylinder coupled to it, at the same time (1-4) (2-3).

This system is a sophisticated evolution of the T. Spark ignition system. It offers the following advantages:

• reduced amount of high voltage wires consequently increasing reliability and reducing electric interference;
• the position and the length of the wires avoid accidental inversion of spark plug wires during servicing.

REMOVAL/REFITTING (Specific for post-modification versions)

• Disconnect the (-) battery terminal.

1. Remove the engine oil filler cap.
2. Remove the fastening screws and remove the ignition coil cover.

REMOVAL/REFITTING (Specific for pre-modification versions)

• Disconnect the (-) battery terminal.

1. Remove the fastening screws and remove the ignition coil cover.

1. Remove the high voltage wires.
2. Remove the fastening screws and remove the ignition coils.

• If required, remove the fastening screws and remove the ignition coil support rod.
• Refit the engine oil filler cap.

1. Disconnect the ignition coil electric connections.
2. Remove the high voltage wires.
3. Remove the fastening screws and remove the ignition coils.

• If required, remove the fastening screws and remove the ignition coil support rod.
