The mass air flow sensor is a component that converts the flow of inhaled air into an electrical signal. It owns advantages of low pressure loss and a wide range of measurable flow rates. The signal is the main basis for the ECU to calculate (control) the amount of fuel injection. Delcoribo produces and sells excellent mass air flow sensors. All of our parts have good resistance to dirt, vibration and extreme temperatures. You can always trust Delcoribo.
