Product Overview
This 4-piece ignition and charging system kit is designed for the world’s most common GY6 4-stroke engines, providing a complete solution for no-start, weak spark, charging failure, or intermittent electrical issues.
Instead of replacing components one by one, this kit renews the entire high-voltage ignition path and voltage regulation system, ensuring strong spark, stable charging, and dependable starting.
All components are manufactured to meet or exceed OEM standards, using high-grade copper windings and heat-resistant polymers to withstand the high-temperature environment of rear-mounted scooter engines.

Fitment FAQ
Will this part fit my specific model and year?
This CDI ignition module is intended for 50cc–150cc Scooters & ATVs (AC CDI System). Key physical/spec details from the product data include AC CDI Box (6-Pin), Connector: 4+2 Pin (Male)System: AC-fired ignition, Converts low voltage into high-voltage spark for improved combustion and throttle response: 3. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this CDI ignition module, also compare the AC/DC ignition type, plug count, pin layout, limiter type, stator pickup compatibility, and mounting space. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this CDI ignition module for machines outside the listed compatibility, or for units with different AC/DC ignition systems, pin layouts, plug counts, or pickup-signal requirements. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the AC/DC ignition type, plug count, pin layout, limiter type, stator pickup compatibility, and mounting space. Recheck listed specs such as AC CDI Box (6-Pin), Connector: 4+2 Pin (Male)System: AC-fired ignition, Converts low voltage into high-voltage spark for improved combustion and throttle response: 3. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Looks like OEM parts, My problem still exists, so more parts required
