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 ### ⭐⭐⭐⭐⭐ Great product *by D***. on August 6, 2025* price, quality, work great on my Toyota Sienna ### ⭐⭐⭐⭐⭐ Did the trick *by J***A on April 21, 2025* It was time for a tune up.
