removed my spark plugs today and noticed that the plugs that are in the centre of each cylinder have the 2 side prongs pointing to the electrodes and the plugs that are on the outside of the cylinders have only an electrode....
Is this correct? Are the 2 outside plugs really worn out?
Look at the part number on the plugs. They should all be the same and the ground points should all be one on each side. If it's the first time you've changed them then previous owner screwed up and replaced 2 thinking there was only 1 plug per cylinder
The ones with just one ground could be iridium plugs

Thank you for clearing this up, new plugs tomorrow
