As one of the world’s leading spark plug manufacturers, NGK SPARK PLUG has been igniting sparks since the 1930s. But sparks don’t just simply ignite. It takes a high amount of precision to create spark plugs that perform their task well and are extremely resistant in doing so.
NGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.
Laser Iridium is designed alongside OEMs to meet quality and durability standards for each manufacturer. Featuring high-grade alumina silicate ceramic and fine wire center electrodes, the Laser Series brings OE performance to every engine.
These spark plugs are equipped with a platinum plate on the middle electrode, which ensures a more constant output of the spark plug over the entire service life, even under difficult conditions. Based on its narrow middle electrode, it emits very little spark voltage, discharges the ignition coil, and ensures optimal combustion.

FEATURES
Spark plugs used for racing must withstand especially hard stresses. The speeds during a race are frequently in excess of 15,000 rpm. Temperature, pressure, and vibrations in the combustion chamber are so immense that conventional ground electrodes could break or melt. For this reason, racing spark plugs often come with specially designed ground electrodes, the most extreme form with a ring-shaped ground electrode. The spark jumps from the middle electrode to the ring-shaped ground electrode.
Efficient High Voltage Transfer
Connecting the ignition coil to the spark plug, ignition leads are a key element in the ignition system of many petrol engines. Thanks to NGK SPARK PLUG’s expertise in ignition technology, the company offers ignitions leads and caps that perfectly complement its wide range of spark plugs and ignition coils.
