Why Choose the Precision Raceworks S58 Port Injection Kit?

As enthusiasts push the limits of their S58-powered BMWs, adding port injection becomes a necessity for supporting higher power levels. The factory fuel system simply can’t keep up, especially with aggressive tunes and upgraded turbochargers. But unlike other port injection kits, this one was designed with seamless integration into the stock S58 intake manifold, making it a direct bolt-on solution—no need for costly custom parts or manifold swaps.

This fully compatible kit provides supplemental fueling, allowing you to safely push your engine's potential with reliable fueling support. Whether you're running high boost levels, ethanol, or other performance fuels, this kit is 100% E85 compatible, offering the flexibility you need for today's modern fuel options.

Key Features & Benefits:

• Seamless Integration: This kit integrates flawlessly with the stock S58 manifold, maintaining the factory look and feel while dramatically improving fuel delivery for port injection. It's as if the car came from the factory with port injection already installed.

• Ethanol-Ready: 100% compatible with E85 and all fuel types, the system includes smooth-bore PTFE lines that are chemically resistant and built to last. Whether you're running pump gas, E85, or a custom blend, this kit can handle it all.

• High-Flow Fuel Rail: Unlike other kits with smaller bore rails that limit fuel flow, Precision Raceworks' fuel rail is AN6 throughout, ensuring maximum fuel flow without restrictions or pressure drops. The rail also features locks that secure each injector to the fuel rail, preventing any pressure-related failures at the injector mounting points. This provides greater reliability and ease of maintenance.

• Injector Security: The fuel rail locks ensure that each injector stays in place under high pressure, removing the force that typically pushes up on the fuel rail. This eliminates the risk of failure, especially where screws attach to the plastic intake manifold. It also makes for a cleaner, more secure fuel system.

• Choice of Injectors: This kit offers a choice between 750cc or 950cc Bosch Motorsport injectors, both modified and flow-matched (static and dynamic). These injectors have been used for nearly a decade by thousands of BMW owners globally, ensuring you get the highest quality, most consistent injectors available.

• Complete Kit: No need to source custom fuel lines or fittings! The kit includes all billet fittings and smooth bore PTFE fuel lines for a long service life, even in extreme conditions. Unlike other kits that cut corners with cheap rubber hoses or plastic fittings, this kit uses only top-tier components for superior reliability.

• Plug-and-Play: Everything you need to add port injection is included in the kit, so installation is straightforward. Pair this system with your preferred injector controller, and you’re ready to go!

• Comprehensive Tuning Support: Whether you're tuning for big power or seeking better fuel efficiency, the kit works seamlessly with popular controllers like the ReFlex Lite and ReFlex Plus. These controllers offer sequential firing of injectors for better fuel trims and more stable fuel pressures, ensuring optimal performance across the RPM range.

Controller Options:

• ReFlex Lite: A simple and cost-effective solution, similar to the AIC controller but with sequential firing. This improves fuel trims, stabilizes fuel pressures, and increases injector efficiency.

• ReFlex Plus: For those seeking more advanced features, the ReFlex Plus offers CanBus integration, the ability to add a flex fuel sensor for true ethanol tuning, and support for a fuel pressure sensor, providing a more precise and dynamic tuning platform.

What’s Included in the Kit:

• AN6 Fuel Rail with locks to secure injectors
• 750cc or 950cc Bosch Motorsport Injectors (flow-matched for optimal performance)
• Billet Fuel Fittings and Smooth Bore PTFE Fuel Lines
• High-Flow Fuel Rail for maximum fuel delivery
• Fuel Rail Locking Mechanism for secure injector mounting
• Injector Controller Compatibility (ReFlex Lite or ReFlex Plus)
• Detailed Certificate of Conformance for injector flow data

Additional Information:

• MPI-specific software tuning is required to fully utilize the benefits of the port injection system.
