Precision Raceworks S58 Port Injection Kit

The Precision Raceworks S58 Port Injection Kit is the cleanest and most reliable way to add supplemental fueling to your G80 M3 / G82 M4—without needing an aftermarket manifold. It installs seamlessly like OEM and is fully E85 compatible.

Choose the kit with or without flow-matched Bosch Motorsport injectors, each set backed with certified flow data for accurate tuning.

What sets this kit apart:

• True AN6 fuel rail diameter end-to-end for maximum flow (no hidden restrictions)

• Exclusive injector lock system prevents injector lift and fuel rail failure under boost

• Smooth-bore PTFE fuel lines and billet fittings—built to handle high-pressure, high-heat environments, long-term

This is the same proven Precision Raceworks port injection platform trusted worldwide—now designed specifically for the S58 platform to support serious power safely and reliably.
