If you are running E85 or ethanol mixes in your BMW, you need this kit!

This is a complete plug and play kit to install a Bluetooth ethanol sensor in your F-Series BMW. (Check compatibility for your platform below)

This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgrade -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer with an optional 0-5 volt analog output for use with the JB4 or analog gauge to monitor your ethanol content.

  • Bluetooth feature is optional and requires our 3rd party Iphone or Android app that must be purchased separately to use this feature.
  • If you are using an Apple product the app can be found by clicking here

For your fuel line upgrade, choose the option that supports your current configuration.

  • HPFP to the fuel tank: (Stock)
    • This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor.
  • Port Injection to the fuel tank:
    • If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel.  Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup.
  • Non-Fuel-It! port injection to fuel tank:
    • Choose this option if you are running a port injection kit that we did not manufacture.  This kit includes a longer 18" feedline from the Y to the port injection rail.  You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail.

All of our kits utilize our custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed.

*These kits are available for off-road use only

*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.

We are typically very quick and have a 24-48 hour turnaround time. Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other.

Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)

Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at info@kiesmotorsports.com

Yes, we do price match reputable competitors in the marketplace. If you find a product cheaper elsewhere, please email us the (1) link of the product from our website and (2) the link to the competitor site. We will make an assessment on our end if we are able to price match or not and respond to you via email.

Typically you have 14 days to return a product you purchase when you change your mind. Damaged and improperly installed products are NOT eligible for returns. Shipping fees may be assessed and not refunded based on criteria as well as restocking fees. Please see our FAQ page for more details.

Unfortunate Kies Motorsports no longer does customer installs (with the exception of crank hubs - we still do thos inhouse). Our HQ is solely reserved for filming, office space, and shipping/receiving.
