Spool Performance S58 Port Injection Kit – BMW G87 M2 / G80 M3 / G82 M4 / G83 M4
Upgrade your BMW S58 fuel system with the Spool Performance Port Injection Kit. Designed for the G87 M2, G80 M3, G82 M4, and G83 M4, this comprehensive package brings together the components needed to add supplemental port injection to your factory plastic S58 intake manifold.
Whether you’re planning an ethanol-powered build or supporting upgraded turbos, this kit simplifies the process with a matched selection of fuel delivery components, sensors, wiring, and a MOTIV Reflex+ controller. No piecing together fittings, tracking down harnesses, or searching multiple suppliers to complete your setup.
An 8AN fuel rail and E85-rated fuel line provide the foundation, while high-quality quick-connect fittings help keep the installation clean. A genuine Continental ethanol sensor and MOTIV fuel pressure sensor provide ethanol content and fuel pressure inputs for your control setup.
Choose Bosch 1000cc injectors supplied with a flow-rate specification sheet or Injector Dynamics ID1050X injectors to suit your build.
