Description
Take your BMW S58 fuel system to the next level with the SPOOL Performance S58 Port Injection Kit – Full Package, a comprehensive supplemental fueling solution engineered specifically for the BMW G87 M2, G80 M3, G82 M4 Coupe, and G83 M4 Convertible.
Designed for high-performance S58 applications, this complete package combines the fuel delivery hardware, ethanol-content monitoring, fuel pressure monitoring, wiring, injectors, and MOTIV Reflex+ sequential port injection controller needed to build a properly integrated port injection system. By bringing the required components together in one package, SPOOL Performance eliminates the need to source individual fittings, sensors, wiring, and control hardware from multiple suppliers.
The system is designed to work with the factory plastic S58 intake manifold and provides a practical solution for builds requiring additional fuel capacity, including ethanol-fueled setups and vehicles equipped with upgraded turbochargers.
Complete S58 Supplemental Fueling Solution
At the heart of the system is an 8AN fuel rail paired with an 8AN E85-rated fuel line and high-quality quick-connect fittings. This fuel-system foundation is designed to provide reliable fuel delivery to the additional port injectors while maintaining a clean and organized installation.
The kit also includes a genuine Continental ethanol sensor and dedicated SPOOL ethanol harness, allowing the system to monitor ethanol content. A MOTIV fuel pressure sensor provides fuel-pressure data to the control system, giving the setup an additional layer of fuel-system monitoring.
MOTIV Reflex+ Port Injection Controller
The included MOTIV Reflex+ sequential port injection controller with universal harness provides the control hardware required to operate the supplemental port injection system.
The Reflex+ system is designed to integrate the additional injectors and sensor inputs into the vehicle's performance-management setup. Proper calibration is required to configure the port injection system according to the specific vehicle, fuel type, injector configuration, and engine modifications.
Injector Options
The full package can be configured with high-flow supplemental injectors to match the requirements of your S58 build.
Available injector options include:
- Bosch Motorsport 1000cc injectors with flow-rate specification sheet
- Injector Dynamics ID1050X injectors
These injector options provide additional fueling capacity for performance-oriented S58 applications and allow the system to be tailored to the requirements of the build.
Ethanol & Fuel Pressure Monitoring
A genuine Continental ethanol sensor is included to provide ethanol-content data for compatible tuning strategies. The included SPOOL ethanol harness and SPOOL 360 quick-connect fittings simplify the sensor installation and connection.
For fuel-pressure monitoring, the kit includes a MOTIV fuel pressure sensor along with an 8AN ORB to 1/8-inch NPT adapter fitting. This allows the pressure sensor to be integrated into the fuel system while providing the Reflex+ controller with the necessary pressure input.
Factory S58 Intake Manifold Compatibility
The SPOOL Performance kit is specifically designed for installation on the factory plastic S58 intake manifold. The included installation tools and drill bit are provided to assist with preparing the factory manifold for the additional port injectors.
Because installation requires modification of the factory intake manifold, careful installation is recommended. Proper injector positioning, fuel-line routing, sensor connections, and system setup are important for reliable operation.
Ideal for High-Performance S58 Builds
Adding supplemental port injection can provide additional fuel delivery capacity for S58 engines operating beyond the capabilities of the factory fueling system. This makes the kit particularly suitable for modified vehicles running ethanol-based fuels or supporting upgraded turbocharger configurations.
The complete package provides the core hardware and control components needed to simplify the transition to supplemental port injection without requiring the customer to piece together a system from multiple sources.
