Genuine Bosch 66lb/hr 725cc 65mm Fuel Injectors (Set of 4)

725cc High Impedance Fuel Injectors – EV14 725cc high-impedance fuel injectors designed for high-performance naturally aspirated, turbocharged, and supercharged applications. These injectors provide consistent fuel delivery, precise atomization, and reliable operation across a wide range of engine speeds and loads. Each injector features a standard-length body with a regular-tip nozzle and single-cone spray pattern. The 12-ohm high-impedance design is compatible with saturated injector drivers commonly used in factory and aftermarket engine management systems. These injectors feature an EV14 (USCAR) electrical connector and are compatible with gasoline and E85. With a nominal flow rating of 725cc/min, they provide increased fueling capacity for modified engines while maintaining consistent fuel delivery and drivability when properly calibrated. Features: 725cc nominal flow class High-impedance, 12-ohm design Standard-length injector body Regular-tip nozzle with single-cone spray pattern EV14 (USCAR) electrical connector Compatible with gasoline and E85 Suitable for naturally aspirated and forced-induction applications Compatible with saturated injector drivers Specifications: Flow Rating: 725cc Class (731 cc/min nominal at 3 Bar) Mass Flow: 500 g/min at 3 Bar Flow Rate: 66 lb/hr at 3 Bar Reference Fuel Pressure: 3.0 Bar (43.5 PSI) Body Length: Standard Connector: EV14 (USCAR) Resistance: 12 Ohms Nozzle: Regular Tip Spray Pattern: Single Cone Fuel Compatibility: Gasoline, E85 Calculated Static Flow Rates: The following flow rates are calculated from the nominal 731 cc/min rating at 3 Bar. Actual flow may vary depending on fuel type, temperature, and differential fuel pressure. 2.0 Bar (29 PSI): 597 cc/min 3.0 Bar (43.5 PSI): 731 cc/min 4.0 Bar (58 PSI): 844 cc/min 5.0 Bar (72.5 PSI): 944 cc/min 6.0 Bar (87 PSI): 1034 cc/min 7.0 Bar (101.5 PSI): 1117 cc/min Installation Notes: ECU tuning is required when installing higher-flow injectors. Injector scaling, dead time, and fuel pressure compensation must be configured for the application. Verify fuel rail dimensions, injector length, connector type, and O-ring compatibility before ordering. Calculated flow rates are estimates based on the square-root relationship between differential fuel pressure and injector flow. They are not individually measured flow test results.
