Changed these along with plugs. Matched the originals I pulled well. Great OEM part. Old ones were a pain to pull off. Made sure to add some dielectrical grease to the new ones to keep voltage and to make them pull easier for next time. Vehicle is running smooth. Came in fast. Work like they are supposed to.

Exactly what I needed and my sputtering problem at stop signs went away. I did both plugs and wires. These are super easy to do yourself.

These are very nice looking OEM plug wires. But they have a huge fall. Once you install them, you cannot take them off again. You will most likely pull the metal connectors right out of the boot. I am very aware of this and I take my time and really twisted around to make sure it is broke free of the plug and all that, but in the case of these wires, there is no avoiding it. So if you are looking to replace your plug wires with OEM, these are it! But you must know that once you install them there is no taking them back off of the plug. And even if you have a bad coil pack down the road, you only need to take the top part off of the coil. You won't need to take it off of the plug. So you'll be fine in the event of a coil failure in the future. But if you ever need to take it off the spark plug, say to do a compression check or change out the plugs or just to check the plugs for some reason to see how your fuel mixture has been recently, your cooked! You're going to ruin the plug wire. And of course you can just stick that metal piece back in there and put the plug wire back on the plug, and you won't have a misfire it will be fine. But there's something unsettling about doing that, and I'm saying this as an automotive technician. I don't like that because it seems like the plug wire can come off of the spark plug easily in the future. ACDelco did replace these under warranty from failing. It didn't fail because of what I mentioned, it failed for some other reason. I swapped out with some other wires from another truck I had here, and the misfire went away. Swapping back I had a misfire. So I had them replaced under warranty and now it's fine. But I need to let you know that you should probably buy aftermarket plug wires. There's nothing wrong with Autolite or Duralast, and some of the best ones out are the Belden plug wires.

came on time were in ACDelco box took me 40 min. to change all 8 on a 2005 Tahoe changed the plugs at the same time one bad wire to get at was the firewall passenger side just pull the 1 bolt holding the dipstick in place will swing out of the way to get your hand on it.

The good quality you'd expect, fit perfectly on my 07 Suburban.
