The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating. While cold-rolled threads prevent cross-threading and damage to cylinder heads and a trivalent plating eliminates the need for anti-seize. Complete with a high-grade alumina silicate ceramic.

One strategy for extending the service life of a standard nickel spark plug is to equip it with multiple ground electrodes. With such spark plugs, the spark continually jumps over to a different ground electrode. In doing so, the wear is distributed to up to four ground electrodes and the service life is extended.
