2007-2013 GMC Sierra Oxygen Sensors

While you might not at first realize it, our 2007 to 2013 Sierra O2 sensors are critical to your truck's performance. For sure, they are not the most exciting parts, but O2 sensors perform a vital function by monitoring the composition of the exhaust gases. The sensors collect that information in real time and send it back to the GMC Sierra ECU, which then analyzes the data before taking action. From there, the ECU might adjust the air and fuel mixture in the cylinders, or change the engine timing, all to optimize performance. The information from the O2 sensors combine with other factors, such as the ambient temperature, driver behavior, throttle positioning, and more to configure the best setup possible. All you need to know is that having O2 sensors which work properly enables your truck and its engine to perform like the champions you know they are. These sensors allow your Sierra to be flexible as conditions change, so you always enjoy optimal performance and the best fuel economy possible. In other words, you benefit from maximum horsepower and torque, and you save money on gas. Of course, the O2 sensors also reduce pollution, so your truck can pass emissions testing in your area without problems. By always getting the air and fuel mixture in an ideal range, the 02 sensors and the truck's ECU prevent unnecessary buildup on the spark plugs, which further enhances performance for the long run. When you choose O2 sensors from AmericanTrucks, you get top quality so reliability and durability aren't concerns.
