Magneti Marelli IWP189 Fuel Injector 490cc
Price:
$231.00
The characteristics of the injector are a fast pulse response, high precision, high dynamic range and optimum fuel atomization. These are achieved by a high performance ON-OFF actuating electromagnet with opposing expansion poles that moves an internal injector valve on high-precision ground cylindrical slides, and a high precision nozzle. The injector has a stainless steel body, a fuel-resistant plastic connector, martensitic stainless steel internal valve and an electromagnet with a low carbon content stainless steel armature. The electrical connection to the control unit is via a Mini-Timer plastic plug.
Applications
Standard equipment on all the following Ducati & Moto Guzzi models
- 848
- 1098
- 1098R (high flow injector)
- 1198
- S4RS -later models
- Streetfighter
- Standard equipment also on many other Moto Guzzi.
Great upgrade option for 749 or 999 which use the single stream yellow injectors as these have a mch better spray pattern with finer atomisation. Will need some re-mapping from stock, however.
