Kinda
I put it into my car and it brought up a red light on the dash saying there’s a transmission fault. I THINK it’s because you need to unplug the battery to get rid of the factory settings so the car will learn the parameters of the new MAF sensor (I read this up online). I haven’t done it yet though because I am a little wary about resetting the factory settings. I put my old MAF sensor back and it worked back normally though.
