Send a strong, high-voltage spark to the cylinders with the ThunderSpark Ignition Coil 921-2280. It installs as a direct-fit replacement for the 2008-2015 Smart Fortwo across the listed applications.
An ignition coil steps up the vehicle's low battery voltage into the high-voltage pulse that jumps the spark plug gap and ignites the air-fuel mixture in the combustion chamber. When the original coil breaks down, that spark can weaken or drop out, so a sound replacement is essential to keeping each cylinder firing as intended.
Core job: transforms battery voltage into the high-voltage output needed to fire the spark plug.
Direct fit: serves as a direct-fit replacement for the original coil on the listed Smart Fortwo applications.
Signs this part may need replacing: engine misfire, rough idle, hesitation, hard starting, a lit check-engine light, or reduced fuel economy — diagnose the cause first, since these symptoms can have other sources. If a failed coil is the cause, this unit replaces it.

What are signs my ignition coil may need replacing?
Misfires, rough idle, hesitation, hard starting, a check-engine light, or poor fuel economy can indicate a failing coil. Diagnose the cause first, as other parts can cause these symptoms.
Will replacing this coil fix my misfire?
If a failed ignition coil is the cause of the misfire, this unit replaces it. Because misfires can also stem from plugs, wiring, or fuel issues, confirm the source before replacing.
