Purchased fuel injectors from them and they turned out to fill up my engine with fuel where it started pouring out of the exhaust. I went an bought some at the auto parts and they worked perfect. When i contacted !A Auto about the problem they asked for all the information for the vehicle and i gave it to them so they can turn around and tell me that they do not take parts that have been installed. How am i supposed to know their part is faulty if I never installed it? They carry cheap but faulty parts. Be aware of the way they do business since they do not stand behind their parts.
