Precision Raceworks Direct Injectors for BMW N55/S55
The Precision Raceworks direct injectors are engineered for BMW N55 and S55 platforms to deliver substantial fuel flow increases without relying solely on port injection. Developed to provide high-volume direct fuel delivery, each injector is tested and flow-calibrated on high-pressure equipment and grouped into precision-matched sets of six.
These direct injectors offer full compatibility with pump gasoline and E85 alternative fuels, supporting high-horsepower builds. Designed as a direct drop-in replacement, they integrate seamlessly with electronic wastegate applications and are widely supported by major tuning platforms including MHD, Bootmod3, and Ecutek.
