Kits for BMW F97 X3 M S58 3.0L

Clear BMW chassis

Please ensure your correct model is selected

BMW fuel system kits provide a comprehensive solution for maintaining and upgrading the fuel delivery system, ensuring optimal engine performance and efficiency. Over time, fuel pumps, injectors, filters, and pressure regulators can wear out, leading to poor fuel economy, hard starts, misfires, and engine hesitation. Common problems include clogged fuel injectors, failing fuel pumps, and fuel pressure inconsistencies, which can result in rough idling and reduced power. Upgrading or replacing worn components with a complete BMW fuel system kit restores proper fuel flow, enhances throttle response, and improves overall drivability. Our selection of OEM and high-performance BMW fuel system kits includes everything needed for a reliable fuel system refresh, ensuring a precise fit and long-lasting durability for a wide range of BMW models.

The Precision Raceworks X3/X3M (G01/F97) Stand Alone Auxiliary Fuel System is the highest-performing and most stable low-pressure fuel system on the market! Forget about how things have been done and embrace the benefits of dedicated fueling for your port injection! Since direct injection came out on modern BMWs, enthusiasts have been adding port injection. With this came the need to upgrade the low-pressure fuel system to keep up. Historically this was done by increasing the output of the main fuel system. Unfortunately, the main fuel pump is controlled using PWM by a factory-programmed controller designed to reduce output when target fuel pressure (typically 5 bar) is exceeded, creating a constant battle when pumps are added or upgraded. This limits upgraded fuel pumps from performing to their full potential. Additionally, the high-pressure pump control system dumps fuel back into the low-pressure system at high pressure low volume resulting in oscillations of the low-pressure fuel system. Because of this, the DI system in the car is required to constantly make corrections to keep target AFR in check. With this stand-alone low-pressure fuel system dedicated to your port fueling that is a thing of the past! Get rock-solid fuel pressures at any pressure, run fuel pressures that are 1:1 scalable to boost pressure, flow more fuel with dedicated lines, run smaller injectors and still get more fuel than you did with large injectors (allowing for higher resolution), put less demand on the car’s DI system to correct for fluctuations in pressure, even your tuner will be grateful as the system makes tuning of port fueling even easier and more accurate, the list of benefits goes on and on! Features & Benefits Billet Aluminum top hat with 3 high-flow fuel ports Dedicated fuel pump(s) for port injection system Optimal pump location resistant to fuel slosh under acceleration Fully adjustable 1:1 scaling billet fuel pressure regulator 10-micron USA made Microglass fuel filter (Ideal for E85) Smooth bore high flow PTFE fuel feed & return lines (AN6) All billet connections for both fuel line fittings and top-hat Plug and play connectors inside and outside* the top hat Configurable pump activation harness (see instructions for more details) Increased injector flow (when using 1:1 regulator feature vs static) Compatible with all stock or upgraded primary fuel pumps Easily expandable and upgrade-able for more fuel All components and parts feature 100% Ethanol Compatibility The AFS.460 dedicated auxiliary fuel system comes with all** necessary components to provide a dedicated fuel system for port injection. Featuring a single Walbro 535 (F9000295) fuel pump which flows 460LPH at 3 bar. Pump flow 43.5 psi-a : 460 lph Recommended base pressure: 43.5 psi-g Maximum Fuel Pressure: 110 psi-g Number of Fuel Output Ports: 2 Number of Fuel Return Ports: 1 Pump 1: Walbro 535 (F90000295) Pump 2: N/A Available (unused) Electrical Connections: 4* Total System Weight: 11 lbs (including fuel lines and wiring harness) *At time of install some wiring in the car may need to be cut and spliced to connectors included in this kit on older models **The AFS kits are designed for use with a port injection kit where the fuel rail is mounted above the manifold.

BM3 is proud to bring out this truly awesome product that makes getting the required Flex Fuel hardware on your BMW with incredible ease and minimal effort, in your own driveway. BM3's kit is entirely plug-and-play with the factory vehicle harness. No cutting or splicing of OEM wiring/connectors. It installs in minutes and can be removed without a trace on the car! BM3's team used SolidWorks to design a Flow Optimized Flex Fuel Sensor Adapter (FFSA) to ensure fuel flow is unobstructed and with no added pressure drop at full fuel pump flow from the fuel tank to your motor when our kit is installed. This is important when pushing the factory fuel system with all the power Ethanol can provide over petrol! Flex fuel sensor housing is designed to neatly install into the factory BMW fuel hat location. Flex Fuel Sensor Adapter also contains two 1/8 NPT ports that allow installation of an auxiliary Fuel Pressure sensor for vehicles that don’t come with an OEM one from the factory for future use. Depending on fitment, either port can be used. Install the BM3 Flex Fuel Plug and Play Kit and flash your flex fuel enabled BM3 OTS MultiMap or Custom Map in minutes and you’re off to the races never worrying about alcohol/petrol blend % in your fuel tank. It does not get better or easier than this! BM3 FlexFuel Plug and Play Kit: Minutes to install at home as opposed to hours at a shop with car up on lift fabricating/cutting into factory fuel lines and splicing/cutting/pinning into OEM electrical 4+ hours in time/cost savings to get going on Flex Fuel as compared to most other kits that require making custom fuel lines, fittings and custom wiring!
