From weekend warriors to accomplished racers, NGK Spark Plugs are sparking winners. Advantages of Iridium Spark Plugs Iridium electrodes, due to their unique properties, can be made to a visually smaller diameter than platinum, Gold and copper/nickel spark plug electrodes without sacrificing the service life of the spark plug. The spark plugs potential difference is concentrated at the minute Iridium tip resulting in lower voltage requirements for the 'spark jump'. In some application this can be as much as 5,000 volts less compared to standard plugs. This reduction in voltage requirement results in improved ignition with less strain being placed on the cars ignition system. Benefits of improved ignition/combustion include improved fuel economy, increased power and acceleration and in particular, faster throttle response. NGK Iridium Spark Plugs NGK Iridium IX Spark Plugs have a centre electrode made from an Iridium alloy with just a 0.6mm diameter. NGK believe this diameter of spark plug electrode gives the ideal balance between performance and service life. Service life can be up to 60000 miles for N/A car motors although the service life can vary greatly, for example an extremely modified car engine can wear out its spark plugs in a few thousand kilometers. |
