The Lotus Elise S 1ZZ engine has integrated coil packs rather than a distributed system.
The original engine design was to have the engine in the front of the car which created more airflow than what we see in the Elise and Exige.

Using the engine in the rear of the car increased the engine bay temperature and of course increased the operating temperature of the coil packs.

When the engine light switches on and you're experiencing misfires specifically on one cylinder, there's a fair chance the coil pack is gone.

Easiest way to identify is to swap the coil pack from one cylinder to the next and see if the problem moves as well.

Our coil packs are fully compatible with the 1ZZ Engine as seen on the Elise S MY2006
