How do you replace the spark plugs on a Renault Scenic?

Hi Scenic owner,
To access to the location, you have to remove engine cover by lifting the front part, ie nearer to you, then pull the cover towards you. This will prevent damaging the cover.
Every spark plugs has its individual ignitor. It can be removed by unfastening bolt size 10mm socket.
Once the ignitor is removed, the spark plug which is inside the plug well can be removed by using the right size spark plug socket wrench.
Hope this help.
