Mass Air Flow Sensors (a.k.a. MAF Sensors) are precision components that measure the amount of airflow entering the intake manifold and must communicate clearly with the Engine Control Module (ECM). Remanufactured MAF sensors with debris from prior use can hinder this communication and cause the vehicle to experience drivability issues. To ensure accurate airflow, precise performance, and longer service life, Standard® and Intermotor® offer a higher-quality alternative: a line of 100% NEW, never remanufactured, Mass Air Flow Sensors.View Full Product Listing

Every Standard® and Intermotor® MAF Sensor is 100% NEW, not remanufactured. All SMP-manufactured MAF Sensors are engineered and built in our vertically integrated TS16949-certified facility. SMP-manufactured sensors are designed with improvements such as thicker walls, upgraded components, and a custom-designed platinum RTD sensor. The result is a line of 100% NEW MAF Sensors that provide highly accurate readings and precise airflow output under all operating conditions.
One of the most important factors for sensor performance is precise testing and calibration. This is what sets Standard apart from the rest. With onsite engineering, design, and test labs at our ISO/TS16949- and ISO14001-certified manufacturing facility, Standard is able to produce 100% new mass airflow sensors that precisely match the OE output and perform flawlessly under all operating conditions. Here are just a few of our testing and calibration techniques:

In addition to testing and calibration, another important factor for performance is the use of high-quality RTD sensors. All SMP-manufactured mass airflow sensors feature custom-designed, platinum flow RTD sensors that precisely match OE outputs, and temperature RTD sensors that match OE specifications more closely than the diodes used by some competitors. Plus, the pull strength of our RTD lead joints not only matches the OE, but exceeds the aftermarket competition. Our RTD components also don't break under extreme vibration.
Our custom-designed platinum RTD sensors outperform the aftermarket competition in vehicle road, air flow, and high-temp degradation testing, which results in proper drivability
Competitor's low-quality RTD sensors failed our vehicle road, air flow, and high-temp degradation tests, resulting in noticeable drivability issues.
Road debris and other contaminants that get past the air filter can coat the sensor’s sensing element. The coating insulates the element, causing under-reporting of airflow off-idle and over-reporting of air at low air speeds. GM systems are the one exception to over-reporting of air mass at low airflow speeds.
Often, technicians first try to clean the mass airflow sensor. Although cleaning a contaminated sensor may seem to bring the performance back, it rarely brings it to 100% operation and accuracy. There are many instances where the internal circuitry is damaged or shorted. In these cases, the sensor needs to be replaced. Because the sensor is a key component to the engine’s fueling strategy, it is crucial that it reports with 100% accuracy to ensure peak performance, fuel economy, and reduced emissions.
