ACDelco GM Original Equipment 41-156 Iridium Spark Plug

Good quality product,

I got these for a good price and they were the right ones for my car very pleased

As advertised

Works like a spark plug

I’ve been waiting on these plugs to finish my car. When I opened the package ALL of the spark plugs that I received are used.

Excelent

These AC Delco spark plugs are a exact factory replacement. The price was FAR LESS than local suppliers. Plugs arrived promptly and were installed without any fuss. What's not to like? My compliments to AMAZON!

Be aware that the OEM number has changed on this product. ACDelco changed the OEM number to 41-156. I believe the old number is 41-123. They do not make that number any more. This is the correct spark plug for the 1.4 engines on the Chevy Cruze 2016-17-18. Be warned, the gap was wrong on three of these. Do not install until you check the gap with a spark plug gap gauge. These are supposed to be factor set. I read some other comments, and others had the same issues. Just blows my mind. These should come ready to go. A person with limited experience may end up breaking the needle tip if they don't know what they are doing. The old spark plugs had a circle but flat base where you did not risk breaking the tip when gapping. ACDelco needs to get their stuff together. Overall, they perform as expected. Usually they they claim these spark plugs can go 100,000. Some manufactures claim never need changing. But, I also change them about 50,000. I was a bit late on them this time at 70,000. But I did notice a difference right away. Had more pick up even in the colder temps. The car should run nice in the summer. As I mentioned in my other comment, suprised they make these for people to buy since people are so entitled and lazy they don't keep up with their cars. 'Why would I do that when I can get a new one every 3-5 years.' And that is the attitude why people don't take care of their cars. Then complain about car payments or pollution. The 'green' people complain, but then go buy another car after 3 years causing more pollution from making the car. But I like to keep my cars till they die. And since I have been working on cars for years, unless I get into an accident my cars run forever. So shout out to the people who value their cars and take care of them.

Perfect as it is stocked

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
