the whole idea is they last longer. Every spark causes the electrode to deteriorate slightly making the gap wider and wider. If there is 4 electrodes as opposed to 1 or 2, theoretically youve got 4 times more life from it.
But, if you think how often you replace spark plugs, is it really worth the extra not to mention that some engines dont like them at all.
The gti actually came with 3 electrode plugs and thats what i put in mine.
