As you may already know, on the Smart Fortwo, access to the engine is from the rear, so from the boot. Unscrew the bolts of the engine cover and remove it. You can already see the first three spark plugs (if you don't know which they are, follow the video).

Now simply unscrew the spark plug and insert the new one in its place, obviously screwing it in. You may already know that your car actually has six spark plugs! Where are the other three? We will tell you. They are located behind the right rear wheel arch, which you will need to remove by unscrewing the relevant bolts.

Again, nothing complicated: unscrew the old spark plug and fit the new one.
