as an Automotive mechanic, I ordered these parts for a customer`s car. Not only did they take longer to arrive than promised, but they were also designed terribly and made our work even harder. The one pro IS that they were compatible for the Chevrolet car as advertised .However, the cons far outweigh that single pro. The parts didn't fit correctly, didn't work as expected, and affected the car's performance negatively. Save your time and money and buy a higher-quality replacement part..See full review
