ACDelco GM Original Equipment D515C Ignition Coil

So the part search in amazon says this part does not fit my 2007 Saturn XR 3.6. I was doubting the system so I cross reference the part with Rock Auto and O'Reilly and it was the same part number. I decide to purchase 6 . Once they arrived I noticed that the part said Denzo and not AC Delco, I got worried . So I took them to the chevrolet dealership parts department and they confirmed that the ignition coil was correct. They said AC Delco outsources some of their parts. Once Istalled the car runs great. so this is the correct OEM ignition coil for a 2007 Saturn Aura XR 3.6 .

I have a 2008 Cadillac CTS that was developing a misfire problem at low RPMS. So I changed all my plugs hoping that would fix it but, it didn't. Then I got a check engine light and the code said that cylinder number 6 was the specific cylinder that was missing. Knowing I had already changed that plug, I went to an auto parts store and purchased a new denzo coil for $75.00. I then swapped the bad coil and it fixed it perfectly. About a month later then engine started missing again.... Counting my remaining cylinders I figured that all new coils were going to cost me almost $400. So I looked to Amazon and found these babies. They are literally the exact same coil (same brand, part number), but at half the price at $37.00 with prime shipping. So I got myself five of them, installed them, and the car has been running smoothly ever since. Thanks for saving me $200.

The parts are original at a lower price

Fired right up and continues to run fine 25k mi later. Easy job. Plenty of youtube videos to help if you're worried about installation.

Easy replacement on my wife's Buick. AC/Delco, so at least theoretically as good as OEM.Only "Negative", might have been nice to include a packet of dielectric grease

There are no more AC Delco coils. No need to over spend! The cardboard box is the only part of this coil that is AC Delco. The coil,inside the box is DENSCO...Made in Japan.In fact,when I removed my original coils, they also were marked Densco,made in Japan. Also,much cheaper at Advance,AutoZone,OReillys. Much more expensive at your Cadillac dealer. Same Densco product.

Not RecommendedI expected them to be GM/ACDelco coils. As others have stated, they are Denso. I didn’t know this because I took the six coils (in the GM ACDelco boxes) straight to the mechanic shop. They didn’t tell me they were Denso, but probably assumed I knew what I was giving them.Maybe this wouldn’t be a big deal, but three of the six I replaced are failing after only several months.I called the ACDelco number provided through Amazon, verifying that yes, they are really selling through Amazon and yes, they do sell the Denso parts. The rep gave me pertinent information to submit a warranty claim. She also told me I could request a refund if I didn’t want a replacement. I already had my car in the shop to have one of the faulty coils replaced and was told the other two need replacement as well.I just received my response from the warranty department that the warranty would not provide a refund, only a replacement. I’m completely dissatisfied with this whole experience.Nowhere in the description at Amazon is it stated these are Denso coils. The claim is they are GM-recommended replacement parts. And "GM Genuine Parts" is on the listing and the boxes they come in.Buyer beware: if they fail (most likely after the Amazon refund period) you will not get your money back.

Perfect fit, easy install, No problems at all!
