The NGK CR9EIX Iridium IX is a high-quality spark plug for sporty and high-performance 2-stroke engines. Thanks to its 0.6 mm iridium electrode, this spark plug delivers a powerful spark, improves combustion, and has a longer service life than a standard spark plug.
The CR series features a 12 mm thread and is used, among other things, on center-spark cylinder heads.
