These plugs are of an advanced design and seem very reliable. The electrode has a four point construction. The spark gap is pre-set at the factory and it is not intended to be adjusted. Adjustment would be virtually impossible owing to the four electrodes that surround the central electrode.

Car is more responsive and better MPG. New coils a couple of months ago improved car a little, new vanos a month before that improved a lot, now new spark plugs have improved the car again. Highly recommend this replacement! 5stars.
