FAQ
- What is a CDI box and why does it matter? The CDI box manages ignition timing and spark delivery; a faulty unit can cause starting issues, misfires, or stalling.

- Do CDI boxes require timing adjustments after installation? Some require timing verification; others are a direct swap. Always follow the manufacturer’s install notes.
- Can I use a CDI box from a different brand? Compatibility is model-specific. Use unit listings that explicitly match your model, engine, and year.
- Is a warranty important for CDI purchases? Yes, a warranty helps cover return or exchange if the unit is defective or incompatible.
