So Far So Good.
Great Item, Quick Shipping, you won't be disappointed in this item. So far so good after a month after being installed. Had 206,000 miles on originals. 2013 GMC Acadia.

One of the TOP brands I 100% recommend
This is absolutely one of the best brands you can buy. It is a brand that I have trusted for a very long time in my vehicles and it is never failed. The durability is long life it fits perfectly as long as you match up the model number it looks fine. You get unparalleled smoothness no misfires. Delphi is a brand that I would recommend 100% of the time

Close to OEM without GM markup helped with idle and power
As others have mentioned, high mileage Chevy/GMC 20xx V6 engines will degrade in performance especially over 100k in mileage. My 2011 GMC Acadia was losing power and I could smell oil burning during idle. After A LOT of work removing intake manifold (easy part) and the valve covers (front and rear - PITA) - found the culprits. Oil smell was unventilated blowback fumes from intakes and a blocked PCV valve. The low performance was due to 2-3 inches of sitting oil in 4 of the 6 spark plug tubes. Oil that sits in these tubes interferes with current delivered by ignition coils. New set of these Delphi ignition coils and new spark plug seals (and spark plugs) and valve covers gaskets and a PCV valve, car has more power and passed my recent smog test. Been running well for about 3 weeks now with these coils and went with brand as close to OEM as possible with Delphi.

Bought April 2023, Two maybe three Dead July 2024 - CORRECTION
I thought Delphi was a good brand. This is the second set purchased and installed on two separate vehicles. Both sets have had failures. The original GM products lasted 140,000 miles and the other lasted 160,000 miles. No more Delphi. OEM (GM, Ford, Dodge) from now on. CORRECTION. Was not bad coil. Found oil in spark plug tube that was causing the coils to short out rather than fire the plug. The coils are working correctly.

Transverse Chevy V6 we are cylinders hard to get to
With these coils, I think it's pretty impossible to know quality. If it works it works. This may be the same as the AC Delco part at about 2/3 the cost but I don't know that for certain, and there are coils about half the price that probably will work fine.There's no way to compare a cheap one with a good one side-by-side. But if you need to replace the rear three on the transverse engine you have a big job ahead of you. Everything on the top of the motor needs to be taken off to get to those cylinders. What a terrible design! On a V8 or straight four it takes just a few minutes. On a transverse motor a good mechanic will take several hours. So the labor will cost you much more than the parts sorry to tell you. And if you start to get misfires jerking/bucking you will have no choice. If that happens even if you don't get a check engine light check for codes. My light did not go on but there was a stored code for a cylinder three misfire and this part needed to be changed.
