Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?

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/Roketa/TaoTao 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 CDI Type: 6-Pin (4+2) AC-Fired Racing Module., 1 x 6-Pin Racing CDI Box., 50cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Revs higher. And the spark was visibly stronger compared with the stock set up. Probably should be the first aftermarket part you add to a bike when considering price and results. It does what it says it will, easy installation and great price.
Installation was a breeze, no surprises or issues. As for performance, well, this isn't really a part to increase your performance; it's a part to CHANGE it. This will give you a bit more of a gradual and healthy initial acceleration, because it's tuned differently than your stock CDI, which probably just tells your vehicle to "GO", as opposed to metering the power strategically. For the price, I'd say it's worth throwing in if you have a junky stock CDI.
