How to Replace the Spark Plugs of the Smart Fortwo?

Model: Smart Smart 450 - Years 1998-2007
Part: Spark plugs

To replace the spark plugs of the Smart Fortwo, open the boot lid so you can unscrew all the bolts securing the rear bumper. By removing the rear bumper, you will be able to lift the carpet that serves as flooring in the boot, under which the engine is located. At its top, you will find the spark plugs, which need to be disconnected from their coils and removed from their respective housing. This way, you can insert the new spark plugs by reassembling all the previously removed parts.
