Precision Raceworks Direct Injectors for BMW S58 / B58 Gen 2
Unlock substantial fueling capability with these high-flow direct injectors engineered specifically for modern high-performance platforms. Delivering 26% greater flow than factory S58 injectors and a massive 60% increase over stock B58 Gen 2 units, they support aggressive power targets while maintaining exceptional low-load drivability. Designed for maximum versatility, each injector is fully ethanol compatible and rated for up to 350 bar fuel rail pressures.
Featuring an advanced 8-hole spray geometry that replicates the OEM spray pattern, these direct-fit injectors eliminate the need for wiring harness adapters or physical spacers. Every unit undergoes rigorous static, dynamic, fine leak, and Pmax operational testing to guarantee tight set matching within +/-2%. Complete calibration data is provided to ensure smooth integration across all popular tuning platforms.
