Perfect Fit: Fixed My Misfire and Smoothed My Idle
I recently purchased this ACDelco ignition coil to address a persistent misfire issue on my GM vehicle. Opting for the Original Equipment (OE) part is almost always the safest and most reliable route for these specific engines. The packaging was secure, and the part arrived in perfect condition without any signs of damage during shipping. Installation was straightforward, taking me less than fifteen minutes with just a few basic hand tools. It fit perfectly into the engine bay, matching the factory dimensions exactly as you would expect from a genuine GM component. After swapping it out, I immediately noticed that the engine idle smoothed out significantly. The hesitation during acceleration that I had been experiencing completely disappeared after a quick test drive. It feels great to have the vehicle running reliably again without having to pay expensive dealership labor rates for a simple fix. The performance is indistinguishable from the original coil, confirming the high quality of this replacement part. I highly recommend this item to any DIYer looking to resolve ignition issues on their GM vehicle with a trusted brand. One last plus was the price for these!

Uses a 9/16 hex socket
FYI, This new sparkplug uses a 9/16 socket. Product was not securely packaged. 1 out of the 4 plugs was out of its box and loose in the oversized package.

Ceramic insulator shattered
3 out of the 4 spark plugs had the ceramic insulator shatter when installing and I returned them only for the seller to charge back the 3 broken ones. I then spoke with Amazon support and got my money back then the seller charged me again??? Super low quality stuff, idk if it’s from being shipped through Amazon but I am a certified technician and have never seen spark plugs just shatter from installation. Had to be very careful removing the spark plugs from fear of the shattered ceramic insulator pieces falling into the cylinder’s. If I could give these 0 stars I would.

I ordered 4 spark plugs 41-156. I received 3, 41-156 and 1 C87 plug wrapped up in a plastic bag. Totally unacceptable. Took car in to have plugs installed and 1 wrong plug. Hadcto search for another plug. The 1st order of spark plugs were not the right ones for my car. Not a happy customer!!! Terry Boegel
