Delphi's Mass Air Flow sensors provide the engine control module (ECM) with continuous information regarding how much and how fast air is entering the engine. This ensures optimal engine performance, increases fuel economy and reduces emissions. What's more is that Delphi is the only manufacturer that offers a mass air flow sensors with dual heated elements, which allow any platform to incorporate mass air flow sensors into its air/fuel system, regardless of ducting assembly. Mass air flow sensors feature fast response, typically less than 15 milliseconds to 90 percent of flow change, for outstanding performance over a wide range of ambient temperatures. Delphi's mass air flow sensors also use multiple sensing elements to eliminate sensitivity to changes in supply voltage and noise on power ground lines, and feature cold sealing available to -50 degree Celsius.
