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 ### ⭐⭐⭐⭐⭐ Still runs nice *by A***X on February 13, 2024* I have replaced old Bosch plugs with this; 1000 km and car is stable and i have no problems with it; Smooth and nice, fuel consumption has dropped; Happy with the price; You get 1 instead of 4 as in the photo; another problem is that if the packaging is dent, you will need to recheck the gap; otherwise nice plugs; ### ⭐⭐⭐⭐⭐ They came quick and work just fine *by J***A on July 12, 2025* Excellent product ### ⭐⭐⭐⭐⭐ Just what my 2011 Chevy Volt needed... *by O***E on December 5, 2024* I got 4 of these to replace the 4 that were in my engine. My Volt had started misfiring and if you have ever had to commute more than 40 miles (each way) for work, then you will understand how traveling 38 miles on surface streets instead of the freeway can really put a damper on your time... these along with a replacement Coil pack (corrosion of the spring contacts inside the boots) and I was good to go again.
