Ignition Coil for the 3.0L AJ20P6 / AJ22P6 six-cylinder petrol engine, part of the ignition system.

The coil is switched by the engine control module and steps the low-voltage supply up to the high-tension voltage required to fire its spark plug. One coil serves each cylinder, so a single failed coil produces a misfire on that cylinder only. Applies to both conventional petrol and PHEV builds of this engine.

Frequently asked questions

What does the LR121788 ignition coil do?
The LR121788 is an ignition coil for the 3.0L AJ20P6 and AJ22P6 petrol engines. It sits on top of the spark plug and delivers the high-voltage spark that ignites the fuel mixture in one cylinder. A failing coil causes a misfire on that cylinder.
How many ignition coils does the 3.0 petrol engine use?
The 3.0L six-cylinder petrol engine uses one ignition coil per cylinder, so a full set is six. This listing is for a single coil. When one fails, many owners change the coil and spark plug together, and some replace the full set if the coils are high mileage.
What are the symptoms of a failing ignition coil?
Symptoms on the 3.0L AJ20P6 or AJ22P6 petrol include a misfire, rough idle, a flashing or steady engine light, and reduced power. A failing coil often misfires under load first. Swapping the suspect coil to another cylinder is a common way to confirm which one has failed.
