Product Overview
Replacement 2-pin fuel injector with cap for selected GY6-style 169cc and 170cc EFI engines used in compatible scooters and related powersports applications.
The injector delivers a controlled amount of fuel into the engine's intake system according to commands from the ECU, supporting normal fuel metering and engine operation.
This unit features a 2-pin electrical connection, approximately 4mm mounting-hole diameter, and a listed 4mm injector inner diameter.
Also listed for selected Jonway GTX 250 / EFI 200 applications, but these applications should be verified carefully by comparing the original injector, connector, mounting dimensions, fuel connection, and physical design before ordering.
Product Compatibility
| Engine / Vehicle | Fuel System | Fitment Notes |
|---|---|---|
| GY6-Style 169cc Engine | EFI | Verify injector and connector |
| GY6-Style 170cc Engine | EFI | Selected compatible applications |
| Jonway GTX 250 | EFI | Verify original injector before ordering |
| Jonway EFI 200 | EFI | Verify exact EFI configuration |
| Scooter / Powersports Vehicle | EFI | Compatible GY6-style applications only |
Engine displacement alone does not confirm fuel-injector compatibility. The injector's physical and electrical specifications must match the original EFI system.

FAQ sur l'ajustement
Cette pièce conviendra-t-elle à mon modèle et à mon année spécifiques ?
This fuel injector is intended for selected GY6-style 169cc and 170cc EFI engines and is also listed for certain Jonway GTX 250 / EFI 200 applications.
Fitment depends on the EFI system, injector dimensions, electrical connector, mounting arrangement, and fuel connection rather than engine displacement alone.
Dois-je correspondre au numéro de pièce OEM ?
No OEM number is provided in the original product information.
Compare the replacement directly with the original injector, particularly the:
2-pin electrical connector
Injector body shape
Mounting arrangement
Fuel inlet connection
Injector tip/nozzle
O-ring or seal locations
Overall dimensions
If your original injector has an OEM number, use it as an additional fitment reference.
À quels modèles ou situations cette pièce ne convient-elle pas ?
Do not assume compatibility with:
Every GY6 engine
Carbureted GY6 engines
Every 169cc or 170cc EFI engine
Every Jonway 200cc or 250cc model
Injectors using a different connector
Applications with different fuel inlet or mounting configurations
EFI systems requiring a different injector flow specification
A physically similar injector does not necessarily have the correct electrical or fuel-flow characteristics.
Que dois-je vérifier avant de commander ?
Confirm:
EFI / fuel-injected engine
Exact engine model where available
2-pin connector
Connector shape and terminal arrangement
Injector body dimensions
Mounting-hole configuration
Fuel inlet connection
Injector nozzle/tip design
Seal and O-ring positions
Original OEM number if available
Original injector appearance
Compare the product photos carefully with the existing injector before purchase.
