Good To Know

Q: How do I know if my CDI box has failed? A: Common signs include no spark, hard starting, misfiring, or intermittent stalling that points to the ignition module rather than the stator or coil.

Q: Is this a plug-and-play replacement? A: It is designed to connect to the stock wiring harness on the listed models, though confirming your connector type and part number before ordering is recommended.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
