BRISK spark plug P1 Premium Iridium+ series

BRISK P1 Premium Iridium+ spark plug is designed for motorcycles, including Harley Davidson and Kawasaki models. Its design features a centre electrode with an iridium contact and a ground electrode made of an yttrium-alloyed alloy with a copper core. Thanks to this design, the spark plug requires low ignition system voltage. An open spark gap into the combustion chamber helps suppress the quenching effect and improves mixture ignition.

Designed for efficient ignition

The design of the BRISK P1 spark plug ensures efficient ignition of the mixture. Combining a centre electrode with an iridium contact and an yttrium-alloy ground electrode with a copper core reduces the demand on the ignition system voltage. The key element is the open spark gap into the combustion chamber, which pushes the spark deeper into the combustion chamber. This solution suppresses the quenching effect, where cold electrodes can extinguish the initial flame kernel, and contributes to better combustion of the mixture.
