This low-pressure fuel sensor is commonly a cause of an "Increased Emissions" warning on the idrive and for check engine (SES) lights on BMW's with the N54 6 cylinder turbo engine or the S65 V8 engine in the M3. It will also fit a limited number of cars with the N55 engine. This sensor can be traced to a number of drivability issues, including cold start running problems, misfires, stumbling, hesitations, and overall rough running. You will likely have a code for the misfires, rich condition, or for the sensor itself. In some cases, the combination of codes can bring about a limp mode. Replacing this sensor is an easy and inexpensive first step if you're having any of these issues. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

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.
