WARNING: CA Prop 65 - Cancer and Reproductive Harm 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.

Refer to your vehicle Owner’s Manual for guidance on when you should change your vehicle’s spark plugs. **Q: Should I change all of my vehicle’s spark plugs at the same time?** A: Yes, when it is time for a scheduled spark plug replacement, all spark plugs should be changed. If a single spark plug is fouled or damaged outside of scheduled maintenance, finding the source of the damage and changing it is recommended. **Q: Can I just clean my spark plugs instead of replacing them?** A: No, ACDelco does not recommend cleaning old spark plugs. Cleaning spark plugs does not repair broken components, chipped insulator tips, and worn electrodes and wires. **Q: What is pre-ignition and can it damage my engine?** A: Yes, pre-ignition can cause serious damage to an engine. Pre-ignition, often accompanied by engine knocking sounds, air and fuel ignite in the engine before the spark plug fires. The condition commonly occurs when old spark plugs are worn or dirty. **Q: Does a diesel engine require a different type of plug than a gas engine?** A: Yes, diesel engines require glow plugs instead of spark plugs. To learn what type of glow plugs or spark plugs your vehicle requires, refer to your vehicle Owner’s Manual for guidance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed a no start issue *by T***E on November 25, 2024* OEM fit, finish and quality.

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. ## Frequently Bought Together - ACDelco GM Original Equipment 41-101 Iridium Spark Plug - ACDelco Professional 9746BB Spark Plug Wire Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/6609157-gm-original-equipment-41-101-iridium-spark-plug](https://www.desertcart.ie/products/6609157-gm-original-equipment-41-101-iridium-spark-plug) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-30*
