Better than others
Work great! Better quality than the cheap alternatives here on Amazon. These are like 14g wire compared to the cheaper alternatives which are like 18g wire.

Worked perfectly on my 2018 3500HD
This part was a life saver. My 2018 Silverado 3500hd started running rough and I took it to be scanned. It read #7 cylinder misfire, after some research and a fuel filter change I narrowed it down to my #7 injector pigtail. #7 is problematic because it is located between the firewall of the vehicle and the exhaust which basically just bakes the wiring over time. I had called Orileys, Autozone, Napa, and the Chevy dealer trying to get this connector. The only place with the correct connector that matched mine was Chevy. It was on back order and was $250. All the other parts stores kept pulling up a completely different style and could not find the right replacement. I installed this in about 2 hours while leaving the negative terminals on the battery unhooked during installation. I made sure to put some electrical contact grease on it before clipping it back in due to the extreme temperature #7 is exposed to. Hooked the batteries back up and it runs better than ever. No issues so far, I would highly recommend this product.

Works and fixed my failed pigtail.
Exactly what I needed and was easy to install for #7 on L5P. Used engine cloth electrical tape to wrap it.

Perfect Replacement
Worked as a perfect replacement for a faulty connector in our truck. Definitely check this part before letting anyone convince you it’s the actual injector.

True OEM replacement and Quality
You get what you pay for, this AC Delco plug is a bit more expensive than knock offs but it is of higher quality. - 14 awg Copper wire vs 18 awg aluminum wire in knock off - Made in Mexico vs China - Higher quality shrink butt splice vs knock off Vehicle wire harness appears to also only be 18awg but the cause of the problem is in the connector crimps that heats up and causes higher resistance and computer fault. The heavier gauge wire and subsequent crimp in the connector can only help mitigate this issue. This review is just to help people make a informed decision and see not all items are created equal and that quality costs
