Mass Air Flow Sensors
Innovative OE design
We build our OE expertise into every MAF sensor we make. Featuring a proprietary temperature compensation design, they offer outstanding performance over a wide range of ambient temperatures. And are fast to respond to changing engine conditions – typically less than 15 milliseconds to respond to 90 percent of a flow change. Innovative, dual-heated elements on specific references also help to ensure optimal performance, fuel efficiency, and reduced emissions
OE engineered and tested
By testing and calibrating to OE specifications, our MAF sensors provide the same accurate readings and airflow output as the OE. Each sensor is tested on state-of-the-art sonic nozzle-testing equipment capturing over 6,000 data points per flow, for optimal calibration accuracy. They’re also flow tested to match the OE for signal stability (noise), temperature compensation (the ability of the MAF sensor to measure airflow accurately from -30°C to 70°C) and electromagnetic compatibility.
Never remanufactured MAF sensor
Some things are better new. That’s why every sensor we make – whether with or without the housing—is built with all-new components and never remanufactured. Remanufactured MAFs are simply cleaned and tested, so any contamination on the sensor may not be eliminated, resulting in inaccurate readings to the ECU.
Greener probe-only technology
It’s often the electronics on the sensor probe that fail, meaning it’s not always necessary to replace the complete part. So we developed a probe-only solution, in addition to a full range of complete units. By eliminating the plastic housing, this provides a greener, more cost-effective and faster repair option.
