  • Genuine Continental ethanol sensor
  • Two stainless steel braided fuel lines with black nylon sheathing to protect your other engine bay components

This kit is compatible with the following

  • 2021+ Mazda 3 SKYACTIV® 2.5L Turbo

    *For the Mazda JB4 platform connect the white wire to position #4 on the JB4 25 pin harness. Select WMI page option 2/3 input to enable.

    *We have also made it optional to purchase all the items ala-cart should you choose but for the kit to work it must include the Fuel Lines, Ethanol Sensor, and Analyzer.
     

    *If you aren't sure whether this kit fits your car, send us a picture of your engine bay with the engine cover removed to info@fuel-it.com

    *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.
