2015-2021 Subaru WRX
This is a Genuine Subaru OEM Mass Air Flow Sensor. If the mass air flow (MAF) sensor or MAF meter in your Subaru 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. This item is available for individual purchase as a direct OEM replacement for the MAF sensor on your 15-21 WRX.
Warranty Disclaimer: Subaru of America will only warranty parts installed on a car that has a matching VIN to that part.
