Review: Fixed a no start issue - OEM fit, finish and quality. I bought these as a last ditch effort to fix a no start issue on my mercruiser. They fixed issues that I didnt realise I had in the first place! After it started up on the new plugs, I took a sigh of relief and quickly realised how smooth the engine was compared to before it stopped working. The picture is of my old spark plugs. If yours look like this, just suck it up and get these new ones. Easy to install, fixes many problems with engine performance, including misfires, no starts, fuel economy, lack of power etc. I wish i wouldve started with these in the first place.
Review: Good iridium plug for workhorse 8.1l - Im using this in my w22 workhorse RV. It's working great so far.

## Questions & Answers

**Q: Are these made in the U.S.A. ?**
A: Yes these spark plugs are made in the U.S.http://www.amazon.com/ACDelco-41-101-Professional-Iridium-Spark/dp/B000BYEKCY/ref=sr_1_1?m=AO3M0V08MAZEF&s=automotive&ie=UTF8&qid=1430223876&sr=1-1&keywords=ACDelco+41-101

**Q: Does this replace ACDelco 41-940 Professional Platinum Spark Plugs in my 2000 Malibu 3.1L GM Engine.**
A: I would Hazzard a quess of no. My plugs were for a 2008 Buick with a 3.8 liter engine. If you take out one plug assuming it is a GM plug, it will have a number on it that can be cross referenced on Google or Amazon.

**Q: will it work for hondas**
A: You would have use the ACDelco spark plug application guide to see if this specific plug fits your Honda.
Regardless of what others have posted, this plug is not "formulated" or "specifically" designed for a GM vehicle.  ACDelco and all other spark plug manufacturers build the plugs to match the engine requirements E.g. thread size, reach (distance the plug screws into cylinder head, heat range ( center electrode shape/length.
This is a good price for an Iridium plug.  Check to see your OEM P/N will cross reference to an ACDelco Iridium spark plug P/N.

**Q: will this work on a 2003 chevy impala with the 3.8 engine?And if so are these plugs already gapped at the right specification?**
A: Yes they will work well with your 3.8 engine.  Usually they are gapped correctly.  Compare them to each other.  If you find one or two that are different,  gap those two like the others.

### ⭐⭐⭐⭐⭐ Good iridium plug for workhorse 8.1l
*by G***7 on July 31, 2025*

Im using this in my w22 workhorse RV. It's working great so far.

### ⭐⭐⭐⭐⭐ Fixed a jerky Equinox along with AC Delco plugs
*by J***R on September 28, 2024*

Recently acquired a 2008 Chevy Equinox that had 21,000 miles. When reaching 50-55mph it would become jerky for awhile until it hitting 60-65mph. I had changed rear differential, transfer case and transmission fluids but the jerky acceleration was still there. I ordered these plugs and also new AC Delco wires and it solved the problem. It was a pain to get to the back three on the 3.4l (getting the boots on the plugs was also a challenge for these three) but worth it. The Equinox drives perfectly now. These iridium plugs should last a long time.
