🔌 ACDelco 748UU Spark Plug Wire Set: Genuine GM Original Equipment Review

There have been many reports of "counterfeiting". These are genuine ACDelco parts. They were purchased through Sold and Shipped by Revain.

Factory wires, no complaints. Are there better lines? Yes. Is it OEM? Yes. I replaced them when making 95k spark plugs. I've always been taught that it's easier to change cords and plugs at the same time. The price is sooo much better than buying from GM

They were more expensive than other options but I prefer to fit OEM parts in my cars. These spark plug wires are OEM replacement parts. I replaced the stock spark plug wires 6 years / 76,000 miles when I replaced the spark plugs. I had them in my 2013 Avalanche and drove about 1,000 miles. They fit and perform as you would expect from a quality OEM part. I only took off one star because these wires were way more expensive than all the other options.

How they perform, hopefully another 90,000 miles like the original kit, time will tell. Update: Cable set installed. Everything fit like it came from the factory, both ends snapped into place

I found that some of the wires were cracked, frayed to the core, and/or I had uncapped some. Having a ready kit certainly comes in handy. The GM I drive came with Delcos and I've never been disappointed with an OEM replacement. This is no exception. The set is well made. Quality fit and finish. Everything fits well. Use the…
