Description
Take your BMW S58 fuel system to the next level with the SPOOL Performance S58 Port Injection Kit, engineered specifically for the G87 M2, G80 M3, G82 M4 Coupe, and G83 M4 Convertible. This complete port injection solution is designed to add supplemental fuel delivery to the S58 engine, making it an ideal upgrade for high-performance and modified applications requiring additional fueling capacity.
The kit is built around a robust 8AN fuel rail and E85-rated fuel line, providing a durable and reliable foundation for supplemental port injection. High-quality quick-connect fittings help create a clean and organized installation while simplifying fuel-line connections.
The SPOOL Performance kit includes Bosch Motorsport 1000cc injectors, providing substantial additional fuel delivery capacity for demanding S58 applications. Each injector is supplied with a flow-rate specification sheet, allowing for accurate injector characterization and proper calibration.
Designed for the Factory S58 Intake Manifold
The kit is engineered for installation on the factory plastic S58 intake manifold, eliminating the need to replace the OEM manifold with an aftermarket unit. Installation requires drilling the factory intake manifold using the included tools and drill bit to accommodate the port injectors.
Proper installation and calibration are essential to ensure the port injection system operates correctly with the vehicle's engine management system.
High-Quality Fuel System Components
An 8AN fuel rail provides the foundation for the supplemental fueling system, while the included 8AN E85-rated fuel line is designed to withstand the demands of performance fuel-system applications. High-quality quick-connect fittings provide convenient and secure connections while helping maintain a clean engine-bay installation.
Bosch Motorsport 1000cc Injectors
The kit includes Bosch Motorsport 1000cc injectors, selected to provide the additional fueling capacity required by high-output S58 builds. Each injector includes a flow-rate specification sheet to assist with proper tuning and injector calibration.
