Spark plug NGK ER9EHIX iridium

NGK ER9EHIX spark plug for YX 4-stroke engines, suitable for all Pit Bike and Dirt Bike engines equipped with a 2-valve cylinder head.

NGK is a renowned manufacturer of high-quality spark plugs with many years of experience. NGK spark plugs are not only proven and tested, they also benefit from the latest technical innovations. Spark plugs are sold individually.

This standard NGK spark plug is an original-type motorcycle spark plug used on most two-wheelers. The reliability of standard NGK spark plugs has led motorcycle, motocross and moped manufacturers to use them as original equipment on their vehicles.

NGK Iridium IX spark plugs, the benchmark for performance and reliability, are directly derived from racing developments. Designed for demanding customers seeking performance, they comply with manufacturers’ specifications.

IX-range spark plugs improve original performance in terms of acceleration, cold-start ease, service life and fuel economy. They are particularly suitable for mildly tuned engines and recommended for sporty riding. Using iridium alloy, a precious metal, reduces the central electrode diameter to 0,6 mm in iridium instead of 2,5 mm in nickel or 0,8 mm in platinum, creating a very fine tip and reducing the required ignition voltage. This ensures faster mixture ignition and protects the ignition system.

The beveled ground electrode reduces the shadow area, where fuel remains unburned, and ensures rapid mixture ignition. The iridium-alloy electrode offers superior resistance to high temperatures and erosion. Its slower wear can provide a service life up to 2.5 times longer than conventional spark plugs. The anti-fouling “2 step” system also provides exceptional performance in urban use and on short trips.
