WHAT IS A DRY IGNITION COIL?

Ever since the advent of modern vehicles governed by engine management systems Ignition Coils have undergone a dramatic change.

The old oil filled cylindrical (wet) coils have been replaced by a dry coil; these come in all shapes, styles, sizes and functions. In every day use they are far more efficient than the old wet coils, but unfortunately they are not always more reliable.

Single Outlet

The first type of dry coil, these were de- veloped for the use of electronic ignition systems.

Multi Outlet / Block coil

Used with distributor less ignition systems; can have two, four or six outlets (still requires ignition leads).

Dry coil complete with a module

Ignition coil complete with ignition module again used with distributor less ignition systems. Can have two, four or six outlets (still requires ignition leads).

Direct plug fit Pencil coils

This is the most recent change in ignition coils. They fit directly on to the spark plug, thus eliminating the need for ignition leads. They tend to be fitted one per cylinder, although some applications do have two outlets supplying a spark to their opposite firing order i.e. 1 & 3, 2 & 4.

Rail Coils

This is the other most recent change in ignition coils. They are situated across the top of the cylinder head with one outlet fitting on to each spark plug. This style again eliminates the need for ignition leads.
