Frequently Asked Questions

Yes, this interval depends on what type of spark plug your vehicle requires. Refer to your owner's manual or contact your vehicle's manufacturer for more information.

Yes, if it is the scheduled time for spark plug replacement.

Yes. Diesel engines require glow plugs because diesel engines operate differently than gas engines. ACDelco Professional Glow Plugs are specially designed to give diesel engines the heat they need for their cold starts. Contact your local dealer, ACDelco service center, or refer the manufacture’s service information.

Yes. When ACDelco spark plugs are manufactured, they are pre-gapped to the correct gap specification.

Not always, but you should inspect your spark plug wires for wear when replacing your spark plugs. Refer to your vehicle owner's manual or contact the manufacturer for more information.

Yes, pre-ignition can cause serious damage to your engine. Pre-ignition is the ignition of fuel before the actual spark occurs, which causes a rapid temperature rise in the combustion chamber that can damage engine components and melt spark plug electrodes. Causes of pre-ignition include but are not limited to a buildup of deposits that can become incandescent in the combustion chamber, improper installation torque being applied to spark plugs, and having spark plugs with a heat range that is too hot for the engine's operating condition.

No, cleaning your old spark plugs is not recommended. Dirty, fouled spark plugs may also have broken or chipped insulator tips, worn electrodes, or worn or missing side wires. These conditions severely affect spark plug performance. Replace your dirty, fouled spark plugs with new ACDelco spark plugs.

Yes, ACDelco has marine spark plugs for many applications.
