Ignition System
WARNING: This page is about a different car, the 2002 Jaguar XKR and 2002 Jaguar XK8. However, it is still accessible from the selected car via links, so may be relevant.
The ignition system consists of eight ignition coils, one per spark plug, each incorporating an amplifier module which is controlled by one of two outputs from the ECM. Each output of the ECM controls four of the spark plug mounted ignition coils, two on each bank.
The 14mm spark plugs, one per cylinder, locate in recesses along the center-line of each cylinder head. The on-plug ignition coils are secured to the camshaft covers and each on-plug coil has its own plastic cover.
