B58 Port Injection Plate – Boost Fueling for High-Performance BMWs

 Maximize Fueling & Power for Your BMW B58 with a Port Injection Kit 

The BMW B58 engine is a powerhouse, but when running higher boost, E85, or big turbos, the stock direct injection system can become a limitation. This B58 Port Injection Plate allows for additional fueling, ensuring proper air/fuel ratios, improved combustion, and more horsepower without fuel starvation.

 Key Features & Benefits:

 Precision CNC-Machined Aluminum Plate – Perfect fit between the intake manifold & cylinder head

 Supports Higher Boost & E85 – Prevents fuel pressure drops in high-power setups

 6 Injector Ports – Compatible with aftermarket fuel injectors for additional fueling

 Direct Bolt-On Installation – No permanent modifications required

 Anodized Coating for Durability – Corrosion-resistant for long-lasting performance

 Compatible BMW B58 Models:

• BMW M140i / M240i (2016-2019)

• BMW 340i / 440i (2016-2019)

• BMW 540i / 740i (2017+)

• BMW Z4 M40i / Toyota Supra A90/A91 (2020+)

 Why You Need Port Injection for B58:

•  Essential for E85 Flex Fuel Conversions

•  Supports 600+ HP Builds Without Fueling Limitations

•  Prevents Lean Conditions at High Boost Levels

•  Works with Aftermarket ECU & Tuning Software

The B58’s factory direct injection system is efficient but maxes out when running high ethanol blends or big turbos. Port injection ensures proper fueling, making it a must-have for serious performance builds.

 Recommended Supporting Mods:

 Aftermarket Fuel Injectors (550cc, 750cc, 1000cc)

 Upgraded Low-Pressure Fuel Pump (LPFP) for E85

 Standalone Port Injection Controller (Split-Second, Reflex+, etc.)
