Few sensors in any car have a higher authority than the Mass Air Flow (MAF) sensor. It is so critical to fuel control that a failed or contaminated MAF can cause an assortment of driveability problems: reduced power and fuel economy, ping, a failed emissions test, and sometimes, a no-start.
If your car suffers from MAF-related bog, stumble, erratic idle, stalling, or an illuminated check engine light, a new Bosch or Genuine BMW MAF can restore lost performance in minutes, and increase fuel economy.
