Product Description

The BLOX Racing BXEF-06514.11-550-4 550 cc Eco-Fi Street fuel injectors are engineered to upgrade fuel delivery on Honda engines equipped with EV14 injector ports, including popular B-Series, D-Series, H-Series, and select F-Series platforms. Designed for street performance and mild forced induction applications, this matched set of four injectors provides consistent flow and atomization for improved throttle response and power throughout the RPM range. The included 1/2" adapter tops and Viton O-rings help ensure compatibility with a wide array of intake and fuel rail systems while sealing securely under typical street fuel pressures. 

These fuel injectors are ideal for engine swaps, street performance builds, and upgrades where factory injectors are no longer sufficient to support increased airflow and power demands. While not recommended for dedicated racing or high-boost applications without proper tuning and supporting modifications, the 550 cc/min rating offers a balance of performance and drivability for enthusiast Honda builds. Before installation, confirm that your fuel system, ECU, and tuning support the 550 cc injectors and that the injector body and adapter match your engine's fuel rail configuration.
