Magneti Marelli IWP069 490cc/min Fuel Injector

The IWP 069 “Pico" top feed injector is a standard production component, tested and selected for racing applications.

Most commonly used in many Ducati Superbike applications, it is well suited to all kinds of high performance engines. It's 490cc/min fuel delivery will support power outputs up to 85HP per cylinder, depending on fuel pressure.

The characteristics of the injector are a fast pulse response, high precision, high dynamic range and optimum fuel atomisation. 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.
