RCEXL 3W Single Cylinder Ignition – 90° CM-6 / 10mm Spark Plug Cap (14mm Hex) with Dual Output Sensor Kit

Specifically engineered for 3W single-cylinder gas engines, this RCEXL ignition system features a 90° spark plug cap for CM-6 / 10mm plugs (14mm hex) and includes the RCEXL Dual Output Sensor Kit for precise, reliable ignition timing.

This advanced CDI unit is optimized for the 3W engine platform, offering smart ignition management across the RPM range. It supports a broad voltage range from 6V to 14.4V and is equipped with Futaba female connectors for battery and tachometer compatibility.

The ignition system offers automated spark timing, with an initial timing of 32° BTDC, and automatic retard to 20° BTDC during low-RPM startups. For easier engine starting, it fires the spark plug twice per cycle at low RPM and transitions to a fixed 32° BTDC after 4000 RPM.
