CDI Igniter Box Fits: Yamaha YFM350 (1997-2001). The spark unit, the igniter, CDI, or TCI module, is the electronic brain that triggers the ignition coil at the right instant. When it breaks down you get a no-spark no-start, a misfire under load, or a cut-out when hot. A fresh unit restores reliable, correctly timed spark. Confirm the connector and model against your original
