## Questions & Answers

**Q: Is there a recommended interval for changing my vehicle’s spark plugs?**
A: Yes, the interval depends on each vehicle model’s specifications. 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.
