Genuine Bosch 57lb/hr 630cc 65mm Fuel Injectors Short Style Extended Tip (Set of 4)

Bosch 630cc High Impedance Fuel Injectors – EV14L 65mm Genuine Bosch Motorsport 630cc high-impedance fuel injectors designed for high-performance naturally aspirated, turbocharged, and supercharged applications. These injectors utilize Bosch EV14 technology to provide consistent fuel delivery, precise atomization, and fast response times across a wide operating range. Each injector features a standard EV14 body fitted with height adapters to achieve the 65mm EV14L configuration, measured center-to-center between the O-rings. Filtered top adapters provide additional protection against fuel system contaminants. These injectors feature a 12-ohm high-impedance coil, EV1 electrical connector, and extended-tip nozzle with a dual-cone spray pattern. They are suitable for gasoline and E85 applications and are compatible with fuel rails designed for standard 65mm EV14L 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. *For methanol applications, flush the injectors with gasoline after use. Methanol should not remain inside the injectors for extended periods. Flow measurements are based on controlled test conditions and may vary with fuel type, temperature, and differential fuel pressure.
