BRISK Platin Spark Plugs are manufactured with platinum contacts on both electrodes or on center electrode only. In the marking system of BRISK Spark Plugs the spark plug with platinum contact on center electrode is marked with "P" and the spark plug with two platinum contacts is marked with "PP".
The platinum on the center electrode ensures stability of electrode distance over a very long time. The small diameter of electrode tip does not prevent propagation of the flame front in the combustion chamber and contributes to increase in engine power. This also suppresses the quenching effect during cold starts.
KEY BENEFITS:
Platinum contacts on center electrode only
Perfect ignition of air/fuel mixture
Platinum on the center electrode ensures stability of electrode
