The Walker Mass Air Flow Sensor program offers replacement sensors in both Sensor Only and Complete Sensor and Housing Assemblies. Sensor only replacement is typically faster and more economical but some manufacturers recommend that you replace the complete housing assembly to ensure the connector air tubes are clean and to protect the sensor itself, which can be damaged by oils on your hands or even air pollution. • Walker Products Mass Airflow Sensors Are Designed To Provide The Vehicles Powertrain Control Module With Precise Information• Sensors Are Engineered Using High Quality Components And Materials To Ensure Proper Fit And Response• All Sensors Go Through An Ongoing Fit, Form, And Function Process And Meet Or Exceed OE Specifications• Walker Products MAF Sensors Are 100 Percent New Units And Tested To Meet Or Exceed OEM Specifications• Limited 90 Day Supplier WarrantyFitment: 2003-2014 Chevrolet Express 15002003-2015 Chevrolet Express 25002003-2015 Chevrolet Express 35002009-2015 Chevrolet Express 45002003-2014 GMC Savana 15002003-2015 GMC Savana 25002003-2015 GMC Savana 35002009-2015 GMC Savana 4500 | Coleman RVP Walker Products Mass Air Flow Sensor
