Fuel-It N20 and N26 Flex Fuel Kits



Please Note: Fuel-It products may have a wait time due to availability.

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 about 30 minutes. (Check compatibility for your platform below)

The kit includes the following:

  • New 5/16" E85 compatible fuel lines for your engine bay
  • Genuine Continental ethanol sensor
  • Fuel-It! Bluetooth analyzer  (Iphone or Android app must be purchased to use this kit)
  • Plug and play harness
  • NOTICE: If you have an N26 motor type, you will need to retrofit the HPFP supply line to part number 13537585415 to be compatible with this kit.
  • We have three options to choose from when purchasing our ethanol analyzers.
    • Bluetooth Only
    • Bluetooth and 0-5 volt Analog for use with the JB4 or analog gauge
    • Bluetooth and 50-150hz Raw Signal for those that are connecting their analyzer to an aftermarket ECU or the DME.  This option puts out the same signal the Continental sensor does.

*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.

DISCLAIMER:  Cancelled orders on Fuel-It products have a 20% restocking fee whether the product has been shipped or not. This is a policy direct from Fuel-It.

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

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.
