The secret of the new Iridium IX spark plug lies in the laser-welded iridium electrode. Thanks to its “minimal” diameter of just 0.6 mm, it concentrates the ignition voltage.
Advantages: The optimal ignition properties of the Iridium IX spark plugs prevent sooting in stop and go traffic. Misfires or misfires are prevented. This reduces pollutant emissions and protects the catalytic converter (if present) and the environment. The Iridium IX spark plugs ensure smooth engine running, increase the driving experience through better acceleration and therefore offer more driving pleasure. The Iridium IX spark plug lasts at least twice as long as any normal spark plug. Frequent spark plug changes are therefore “out”. This in turn reduces costs. Maximum ignition reliability, uniform combustion, optimal engine performance, spontaneous throttle response are the result of the latest technology and reduce fuel consumption. The optimized electrode shape reduces the ignition voltage requirement, protects the engine and ensures "smooth" running.
