NEW REVHIGH Mass Airflow Sensor lineup made in the USA is an OEM direct replacement and uses CERAMIC PCBs to provide the best product with added enhancements.
Features & Benefits:
Resistors are digitally calibrated for optimal precision
Superior thermal stability under even the most extreme under-the-hood temperature changes
Higher consistency in voltage readings at all rpmsMore efficient heat dissipation to extend the service life of the component
Double binding for improved sensor reliability
 
Replacing the Complete Housing Assembly instead of the Sensor Only ensures the connector air tubes are clean and protects the sensor element, which can be damaged by air pollution or oils on your hands. Check for Vacuum Leaks First!

Vacuum leaks present symptoms similar to a faulty MAF Sensor. When replacing the MAF, always check for vacuum leaks, too. Common sources include:
Cracked or loose Vacuum Hoses / Connectors - an audio Stethoscope can help detect air induced sounds from vacuum leaks.
Leaking Intake Manifold Gasket (found in the "Engine" category) - Vacuum Gauge readings below 17-22 in-Hg (normal manifold vacuum at sea level) at idle may indicate an intake manifold gasket leak.
Note: As elevation increases, readings decrease. Subtract 1 in-Hg from normal manifold vacuum reference for every 1,000 feet increase in elevation above 2,000 feet.
Stuck open PCV Valve - remove the PCV Valve and gently shake it; if it does not rattle, the valve is clogged or dirty and should be replaced.
Cracked Intake Boot (found in the "Engine" category)
