🔌 ACDelco GM OE 726UU Spark Plug Wire Set Review

Installed a harness last weekend. They were exactly the same as the original set, which had clocked up almost 101,000 miles. I hope to get the same on this set.

Terrible quality! . The parts are terrible. Doesn't last long and the warranty system is a joke. Don't buy batteries here and expect them to last a long time. I'm sorry for your luck. Buy somewhere else!

Spark plug wires fit the Impala 2003 perfectly, you can already see the difference in drivability and fuel economy. I definitely recommend changing the cables after 100,000 km. 50€ saved compared to dealer.

I received my order quickly. Haven't used this product yet but I trust this brand so I'm sure it will work on my machine. The only problem so far has been that the plastic bubble wrap postal bag has been left partially open. Happy with the order so I ordered more parts.

You simply can't go wrong with AC Delco components on GM vehicles. I've learned the hard way that any other brand of plug wire can throw you through with random misfires and bad idle. There's a reason Delco's products cost a few dollars more, and their products are worth it. Connector wires, coil packs, thermostats, everything should be AC Delco on your GM.
