2017 BMW X4 mass air flow sensor

The middle asking price for a used one is $38.66, across 21 live eBay listings for the 2015–2020 generation. Half of them ask between $26.99 and $49.00. That’s what sellers are asking, not what buyers paid. Sold prices aren’t published anywhere you can count on, and asking prices usually run about a quarter higher than what things sell for — so we say which one this is.

How it comes off

  1. Unplug it.
  2. Remove the screws holding it in the intake tube, or loosen the clamps on its housing.
  3. Lift it out without touching the sensing wire inside.

The usual order on most cars. A 2017 BMW X4 may hide a screw or a clip somewhere else: if a piece will not move, look for what is still holding it before you pry harder.

What to bring for it

Typical sizes, not a promise for every car. Everything to bring to a pull-your-own yard.

Is it worth pulling?

That depends on what the yard charges for it and how long it takes to get off the car, and on where it sits against the other 81 parts on a 2017 BMW X4 that have a market. The full sheet for this vehicle ranks all of them by what you save and by what you clear.
