Precision Raceworks S58 Port Injection Kit – BMW G8X M2/M3/M4

OVERVIEW

Adding port injection to the S58 has traditionally meant sourcing an expensive custom manifold. The Precision Raceworks S58 Port Injection Kit solves that by working with the factory manifold — installing cleanly enough that it's barely visible once reassembled, and built around the same AN6-bore-throughout fuel rail design PRW uses across their B58 kits, avoiding the pressure-drop problems seen in cheaper plate-style kits.

SPECS

• Works with the factory S58 manifold — no need to purchase an aftermarket manifold
• Full AN6 fuel rail — true AN6 bore throughout, avoiding the pressure-drop problem seen in cheaper kits
• Injector-locking rail — built-in locks secure each injector against fuel pressure force and allow rail removal without excessive spillage
• Available with or without genuine Bosch Motorsport injectors (750cc or 950cc)
• 100% compatible with E85 and other ethanol blends
• Available in Black, Blue, or Silver anodized finish

PARTS INCLUDED

• Full AN6 fuel rail with billet fittings and injector locks
• Smooth-bore PTFE fuel lines with stainless/nylon braiding
• Genuine Bosch injectors with certificate of conformance (injector-inclusive configurations)

TECH RESOURCES

• Installs seamlessly like a factory part — no aftermarket manifold needed
• Requires an injector controller to drive the port injectors — compatible with Motiv Re|Flex Lite/Plus, AIC, and JB4 controllers (not included)
• Install guide (video): PRW S58 Port Injection Kit installation guide (YouTube)
• Adding port injection increases fuel demand beyond what the factory low-pressure system can reliably sustain at higher power — pair with the matching Precision Raceworks Stand Alone AFS for your chassis: M3/M4 (G80/G82), M2 (G87), or X3M/X4M (F97/F98)
• Professional installation and a proper tune are strongly recommended
• Not for sale or use in California on any pollution-controlled vehicle per CARB
