Toyota Coil On Plug (Yaris / ZZ) Ignition Coil
Haltech does not sell this part.
For simplicity this ignition coil will be referred to as the ZZ Coil.
The ZZ ignition coil is a high output inductive coil with an internal igniter module designed to be installed directly on top of the spark plug. These were found on many Toyota engines from the late 1990's through to current engines, and are commonly used in the aftermarket for coil conversions due to their high output and coil-on-plug design. They gained popularity due to be available on the very common and cheap Toyota Yaris 1NZ engine, and also the 1ZZ and 2ZZ engines from the Corolla. Most Toyotas of the period used the same coil design with different connector angles and tube lengths.

Suggested dwell time for ZZ coils
12V Power Supply
The ZZ coil can draw up to 8A. If high rpm and high power is being used, together with conventional 30A Relays to provide power, it may be necessary to have a separate fuse and relay for every pair of coils. This is rare but it is possible.
If the wiring is also not cable of supplying the current required it can also limit the spark output.
