Arrowhead Electrical CDI Module

The Arrowhead Electrical CDI Module (capacitor discharge ignition box, also called a CDI box or ignition control module) is a replacement ignition component for powersports engines. The CDI module controls spark timing and delivers the high-voltage pulse to the ignition coil. This keeps the engine starting and running as designed.

Key Features:

• Capacitor discharge ignition design that manages spark timing and energy delivery
• Replacement unit for a worn or failed factory ignition module
• Made by Arrowhead Electrical, a supplier of aftermarket electrical and ignition parts for ATVs, motorcycles and other powersports equipment
• Each part number in the line is built for a specific application, so you can choose the module that matches your machine

A failing CDI module can cause hard starting, no spark, misfires or stalling. Replacing it can restore reliable ignition performance. Choose the variant that matches your machine's application.
