I changed the spark plugs today at about 32k mls (516xxk km).
Removing the ignition coils is no that big problem as it is here sometimes posted
A flat screwdriver, a little bit feeling and power in your hands, „plopp“
No special tool, no wire hanger, no nut and crowbar as an extension.
The biggest headache gave me that damn 8th plug on the passengers side
That‘s no fun
But I did the job and I‘m happy the car is still running
