To run, your GMC's engine needs three things: a spark, air, and fuel. These 2007 to 2013 Sierra mass air meters address the need for the proper amount of air. Too much or too little air can cause your truck's engine to run rough, lose power, and waste gas. In some cases, not enough air means your engine won't start at all, leaving you stranded. That's why a well functioning mass air meter is essential. Because your engine is controlled by a computer, the ECU, it needs a way to measure just how much air is flowing into the cylinders at any given moment. Airflow is affected by quite a few factors, including air temperature and throttle position. Based on how much air is coming in, the computer calculates just how much fuel to inject, maximizing power and efficiency. If you add any performance upgrades such as a cold air intake, larger throttle body, or a forced induction system, the mass air meter helps the ECU adjust so your GMC Sierra keeps running smoothly. For all these reasons, when you have a problem with your mass air meter, you need to do something about it. After all, your truck has been designed to tow and haul like a champ, but something this small can seriously hurt its potential. We offer only high quality mass air meters from manufacturers that have demonstrated precision and a dedication to reliability. You can place your trust in these components, ensuring your truck runs strong for quite some time.
