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 ### ⭐⭐⭐⭐⭐ Excelente producto *by E***O on 9 December 2025* Originales ### ⭐⭐⭐⭐⭐ Perfect fit *by J***O on 9 February 2026* ### ⭐⭐⭐⭐⭐ OEM parts *by S***E on 5 July 2024* ## Frequently Bought Together - ACDelco GM Original Equipment 41-114 Iridium Spark Plug (Pack of 1) - General Motors ACDelco Genuine Parts 19431551 Sparkplug Wire Kit - Permatex 22058 Dielectric Tune-Up Grease, 3oz. - High Performance Dielectric Grease Used To Protect Terminals, Spark Plugs, Wiring And Other Electrical Connections Against Salt, Dirt, And Corrosion --- ## 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.co.uk/products/77650077-acdelco-gm-original-equipment-41-114-iridium-spark-plug-pack](https://www.desertcart.co.uk/products/77650077-acdelco-gm-original-equipment-41-114-iridium-spark-plug-pack) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
