What kind of spark plug does a Jaguar XJ use?
This part is also sometimes called Jaguar XJS Spark Plug. We stock spark plugs parts for most Jaguar models including S Type, X Type, XJ8, XJ6, XK8, Vanden Plas, XJR, XF, XKE, XKR, XJ12, XJ, Super V8, XFR, XK140, Mark VII, XK, XK150, 420, 3.8, Mark IX, Mark X, XJRS, D Type, XK120, 340, Mark V, 2.4, 3.4, Mark VIII, C Type and XKSS.
Why does my XJS ignition system not work?
It might also struggle around the peak torque point. Although the V12 constant energy ignition module is fairly tolerant (it runs OK with the blanked second coil removed – albeit with a loss of spark energy) the ignition system will behave oddly if the coil is not the correct load match.
How many cylinders does a Jaguar V12 have?
The Jaguar V12 H.E. has 12 cylinders, turns at 6500 RPM, and has 11.5:1 compression, making it one of the biggest challenges for an ignition system in production automobiles. To cope with this, Jaguar has incorporated some sophisticated ignition technology.
Where is the auxiliary coil in the XJ ignition system?
The auxiliary coil, located in front of the radiator, is not a spare or a backup; it is designed into the system for producing a good spark. If either coil goes bad, the performance will suffer. Since mid-1989, XJ-S’s have gone to a Marelli ignition system that also uses two coils.
