Subaru OEM MAF Sensor 2015-2021 WRX

Factory Subaru mass air flow (MAF) sensor for FA20 turbo cars.

If the mass air flow sensor or MAF meter in your 2015-2021 Subaru WRX is failing, you’ll notice in addition to the check engine light that your engine may crank and not start, or that the engine speed surges at idle.

Fits all 2015-2021 Subaru WRX, and 2014-2018  Forester XT.
