Subaru OEM MAF (02-07 WRX/STi)
The Subaru OEM MAF Sensor has to be in 100% proper working order for your vehicle to behave properly. Ar you noticing any issues with fuel corrections and/or your tuner not being able to tune the car easily? Are you getting any of the P0100-P0104 Codes? Chances are your MAF needs replacing.
