Californian developer of natural gas engine systems, Omnitek Engineering is introducing longlife spark plugs specifically designed for the demanding conditions found in natural gas engines. The spark plugs feature a center electrode made of Iridium, and a Yttrium enhanced ground electrode. Iridium and Yttrium are extremely resistant to erosion, which Omnitek says guarantees a virtually unchanged electrode gap for the life of the spark plug.
Primary applications are turbocharged natural gas engines where ignition requirements are at their most extreme and a long service life is desired. Wear resistant Iridium/Yttrium electrodes apparently offer reduced voltage requirement and reduced gap wear which Omnitek says increases service life, improves combustion characteristics and lowers susceptibility to misfires. The spark plugs have a factory pre-set electrode gap.
