spark plug question

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.... White Light Fastener Gas Auto part

Is this correct? Are the 2 outside plugs really worn out?

T.I.A.

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

The proper ones are CRE8K
