Detailed Description

The Standard Ignition KS447 flex fuel sensor is built for vehicles that rely on ethanol content measurement to manage fuel delivery and engine calibration. It is a direct-fit replacement for applications including BMW 740i, BMW X5, BMW 330i, BMW 540i, Mini Cooper Countryman, and Toyota GR Supra. This part cross-references OE-style numbers such as 89615WAA01 and 13627636937 for the same application. If you are replacing a failing flex fuel sensor on a BMW 740i xDrive, BMW X1, or Toyota GR Supra, KS447 provides the correct connector style and mounting format for the listed vehicles.

What It Is Used For

• Incorrect ethanol content readings
• Fuel mixture or calibration faults tied to flex fuel signal loss
• Check engine lights related to fuel composition sensing
• Hard starting or drivability issues caused by inaccurate fuel data
• Replacement of a damaged sensor housing or connector interface

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style before installation. This sensor uses a direct mounting method with a female connector and male blade terminals, so the vehicle harness must match the OE configuration. Confirm fitment by year, make, and model before ordering, especially on BMW 230i, BMW 430i, BMW 530i, BMW 740e xDrive, Mini Cooper Clubman, and Toyota GR Supra applications.
