Precision Raceworks S58 Port Injection kit with stock manifold compatibility is Exactly what you G80 M3, and G82 M4 guys have been waiting for. Safely add fuel to your S58 engine to ensure reliable fueling under all circumstances. This kit is capable of providing supplemental fueling to all BMW’s equipped with the S58 engine so that you can push the limits without the need for purchasing an expensive custom manifold.

Kit integrates seamlessly into your car like it left from the factory with it installed. It includes everything needed to add multi-port injection and is 100% e85 compatible. Included are genuine Bosch Motorsport injectors that have been modified & flow matched (both static and dynamic) rivaling the quality and consistency of even the best injectors on the market. A Detailed certificate of conformance is included with each set our injectors giving you all flow data needed for optimal tuning.

What makes the Precision Raceworks port injection different from others on the market?
In this kit the fuel rail is AN6 all the way through unlike some other kits that have AN6 connection but have a much smaller bore reducing flow which can result in pressure drop at the injector.

The Precision Raceworks fuel rail is the only rail currently on the market that features locks which secure each injector to the fuel rail. This removes 72+ PSI of force pushing up on the fuel rail preventing potential failure where the screws attach to the plastic intake manifold. Additionally the locks allow the rail to be removed without fuel going everywhere.

• All kits come complete with ready made custom fuel lines. No cheap rubber lines or plastic fittings involced.
• Smooth bore PTFE to last in extreme conditions with all fuels
• Billet fittings
