SPARK PLUGS WITH PLATINUM CONTACT
Wide range spark plugs with center electrode and platinum contact. Perfect ignition of air/fuel mixture. Extended replacement interval.
Replacement interval: see the table below.
The platinum on the center electrode ensures stability of electrode distance over a very long time. The small diameter of the electrode tip does not prevent the propagation of the flame front in the combustion chamber and contributes to an increase in engine power. This also suppresses the quenching effect during cold starts.
