Flex Fuel Sensor

The Chevrolet Performance Flex Fuel Sensor, part number 13577379, is an OEM GM component designed for flex-fuel vehicles. By accurately measuring the ethanol-to-gasoline ratio, the ECM can make real-time adjustments to optimize engine performance and efficiency when running on various fuel blends. This particular sensor features short, 3/8" inlets, making it a specific fit for certain GM applications. It is manufactured to GM OE standards, ensuring the quality, reliability, and durability expected from factory components. The sensor's role is vital for vehicles equipped to run on both gasoline and E85 (or other ethanol blends), ensuring the engine receives the correct fuel-air mixture regardless of the fuel composition. While the product is listed as GM CAR - UNIVERSAL by some retailers, specific fitment data indicates compatibility with certain 2012 Buick LaCrosse, Regal, and 2012-2013 Verano models. It is a GM-recommended replacement part for those vehicles requiring this specific component. Always verify compatibility with your vehicle's year, make, model, and engine specifications before installation.
