I am a return customer with a C7 and 6th gen Camaro. Recently wanted to put both cars on a flex system. Matt is very knowledgeable and always available to help and ask silly questions.

GM Sensor and GM fuel line. Wire harness seems to be made of good quality and the connectors appear to be OEM. No need to pay more for a brand name kit. This works perfectly.
