Spectra Premium Mass Air Flow Sensor for 2011 BMW 1 Series M – Intake fv. DELIVER UNPARALLELED PERFORMANCE: This Mass Air Flow Sensor (MAF) is built for performance, accuracy, and extended life. The air mass sensor detects the amount of air drawn into the engine and sends a signal to the engine control unit (ECU) to calculate the exact amount of fuel to deliver to the engine. The platinum wire-sensing element responds rapidly to changes in air flow for better engine efficiency and reduced emissions. IMPROVE PRECISION: A fine platinum wire-sensing element coated with a glass film protects the sensor from contaminants and reinforces reliability. Other components reduce exposure to the sensing unit and improve detection accuracy. Their products are designed for drop-in fit and easy installation. They use the highest grade material in production, and all products are performance, endurance, and leak tested. Their manufacturing meets or exceeds OE specifications for fit, form, and function.
