These high-performance spark plugs operate based on the state-of-the-art surface air-gap principle. It is the first spark plug with four thin ground electrodes and a sharpened, silver-plated central electrode.
This technological superiority is also evident in the engine's performance, in all driving situations, over the entire life of the spark plug.
An
Overview of the Benefits:
Noticeably
improved acceleration
Significantly smoother engine
running
Superior engine elasticity
Factory pre-gapped
electrodes
Higher ignition reliability thanks to eight possible
ignition gaps
Self-cleaning thanks to surface air-gap
technology
Increased thermal range: up to three times as many cold
starts possible as with conventional spark plugs
Increased
environmental protection and protection for the catalytic converter

1. Unbox the new spark plug
2. Do not lubricate the thread. Screw in the spark plug by hand until it is seated at the cylinder head.
3. Then the spark plug must be tightened and the mandatory, type-specific torque, e.g 23 Nm.
