Is there a recommended interval for changing my vehicle’s spark plugs?

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.

Should I change all of my vehicle’s spark plugs at the same time?

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.

Can I just clean my spark plugs instead of replacing them?

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.

What is pre-ignition and can it damage my engine?

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.

Does a diesel engine require a different type of plug than a gas engine?

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.
