Images from a Cayman.
There is very little access to get at these with the n/s/r being the worst out of the 2 sides .
Its ok to change the 2 rear plugs say jacked up , on stands and through the gap in the pictures but both front plugs , 1 and 4 need to be done from underneath and your arm up and over the exhaust ... hence a ramp is best , you need to remove the rear undertray ( last picture shows access ).
The spark plugs on these extend into the heads further and as such you can get carbon build up on the plug threads ..
This means they are very tight to unwind .. they fight you every inch of the way and at times you have to wind them back in to free them off.
Not always as in this case x1 bank was tight and the other wasn't .. slight running issue methinks there looking at the plugs .
In short .. you will need a large ratchet ( in the picture ).
Coils are held in place by a T30 bolt which is ally ( non magnetic so don't drop it ) ..
This type of coil does not suffer from corrosion so i never recommend replacing all 6 even in the event of a single one failing .
You will need various extensions flexi and straight ended , t30 socket , flexible plug socket and small / large ratchets .. a long flat bladed screwdriver helps get the electric plug off ..
Push the tab and then with the screwdriver lever the plug upwards .
Pictures show what i use .
With chrome then open the pictures in a seperate tab .. much better image that way .
