2-Pin Fuel Injector with Cap for GY6 169cc 170cc EFI Engine
Verfügbarkeit für Abholungen konnte nicht geladen werden
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.

Passform-FAQ
Passt dieses Teil zu meinem spezifischen Modell und Baujahr?
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.
Muss ich die OEM-Teilenummer verwenden?
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.
Für welche Modelle oder Situationen passt dieser Teil nicht?
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.
Was sollte ich vor der Bestellung überprüfen?
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.
