Best price around and well worth it
i searched every parts store a lot of online stores and could not fine a better deal. What I paid for all 6 Ignition coils I could only have got one any where els. And my car runs better than it ever had before very happy with my purchase and would definitely highly recommend buying from 1 A Auto Part to every one. I called and was one the phone for maybe 5 min and received my parts 2 days later (that was with the over night shipping) well worth it

Ignition Coils
I would recommend the Ignition Coils for the Caddys they fit great and was easy to install. They made the car run better than when I purchased it. And the service was great. The parts arrived when they were suppose to and in great shape

You get what you paid for
Installed a set of these cheap coils on my 09 Enclave. Ran fine for a couple hundred miles then began an occasional miss that got worse. Reinstalled my old coils and runs fine. Lesson learned.

The Replacement Ignition Coils
The initial tooling around town is going quite smooth. The necessity for the coils became apparent when the Caddy failed the bi-annual emissions test. After a complete tune-up,; plugs, cleaned throttle, replace fuel filter etc. The ride is hesitation free but the test for the performance will come when I am able to put it on the road for a road trip. To be continued

I drove the car to Virginia which was about 300 miles and everything is running fine... the big bonus is that the parts was a lot cheaper than my neighborhood auto parts store so i saved over 50% on the cost of the parts which I was very happy with ... I will be ordering more parts in the future for sure .. A big thanks to all you guys at A1auto ... Yours truly. #TRANSPORTERCHARLIE Philadelphia. Pa.

Product not compatible, but I made it work.
The bolts that came with the coils did not fit and it snapped off inside creating a major headache. Frustrating set back. Had to go to hardware store to find correct bolts. But For the price, I still think it was worth the trouble.
September 17, 2018
I will order again from 1A Auto, no problems at all. The price was very competitive.
