Product Details

Are you running more E85 or making more power on pump gas than your HPFP (High-Pressure Fuel Pump) can support?

Fuel-it has developed a port injection kit for your S55 that will provide you with the additional fueling capacity that you need to be able to run up to 100% E85 on stock or upgraded turbos.

What is port injection?

Port injection is a kit that is installed between your intake manifold and the cylinder head that runs off the low-pressure supply to provide you with more fueling than your stock system is capable of.  It's a relatively easy system to install and does not require any permanent modification to your car.

Port injection kits are offered in five different packages to meet your needs:

Base port injection kit: (included in Bronze, Silver or Platinum Kits)

  • Fuel-It! custom black anodized spacer for the intake manifold
  • Fuel-It! custom black anodized fuel rail
  • Black anodized aluminum and stainless steel hardware
  • Dual fuel supply port for those that are running inlets in the stock location (email us for info)
  • Optional return port for those that will be running an upgraded fuel pressure regulator 
  • Six of the following:
    • Flow matched Bosch injectors (52#)
    • Extended length steel bolts for mounting your new spacer 
    • BMW OEM gaskets

Bronze kit includes:

  • Base port injection kit
  • Basic fuel line connection kit
    • Two custom Fuel-It! fittings to maintain your stock fuel line connections at the HPFP and the feed line as it enters the engine bay
    • -6an (3/8") upgraded fuel lines
    • High flow custom Fuel-It! "Y" adapter
    • -6an fuel rail connection

Silver kit includes:

  • Base port injection kit
  • Basic fuel line connection kit​
  • An upgraded fuel line that completely replaces the stock fuel line

Platinum kit includes:

  • Base port injection kit
  • Basic fuel line connection kit​
  • An upgraded fuel line that completely replaces the stock fuel line​
  • Integrated ethanol sensor​
  • Bluetooth and JB4 compatible ethanol analyzer
    • JB4 integration compatible 0-5volt
    • Bluetooth (iPhone or Android app must be purchased to use this feature)

*These kits are available for off-road use only

*All port injection kits are built to order.

*Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated, your ethanol readings may be artificially elevated.
