Review on 🔥 ACDelco GM D515C Ignition Coil: Genuine Original Equipment for Improved Performance by Randy Butler

I have a 2008 Cadillac CTS that was having problems with misfires at low rpm. So I changed all the spark plugs hoping that would fix the situation but no luck. Then my check engine light came on and the code said cylinder number 6 was the specific cylinder that was missing. Knowing I had already replaced that spark plug, I went to an auto parts store and bought a new $75 Denzo coil. I then replaced the broken coil and it fixed it perfectly. About a month later the engine cut out again. After counting the remaining cylinders, I figured all new coils would cost me nearly $400. So I went to Revane and found these babies. It's literally the same reel (same brand, part number) but half the price - $37 with shipping. So I bought five of them, installed them and the machine has been running flawlessly ever since. Thanks for saving me $200.
