Specs At A Glance

Good To Know

Q: How do I know if my CDI box has failed? A: Common signs include no spark, weak or intermittent spark, and an engine that cuts out once warm. Testing the module against the service manual procedure confirms the diagnosis before replacement.

Q: Is this a plug-and-play replacement? A: It uses the factory connector and mounting layout, so installation is a direct swap on compatible models. Confirm your machine's model year and part number before ordering.

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