To replace the spark plugs on a Smart Roadster, open the rear hatch to access the engine located underneath. Disconnect the connectors attached to the injectors so that they can be removed from their housings by unscrewing the securing bolts.

Once the injectors are removed, you can pull out the underlying spark plugs from their housings, replacing them with new spare parts. After replacing the spark plugs, refit the injectors, connecting and securing them properly.
