| FAQ - Answer 1 | 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. |
| FAQ - Answer 2 | Yes, if it is the scheduled time for spark plug replacement. It is okay to replace one spark plug if it is fouled or damaged prior to scheduled maintenance, provided the source of the damage is found and corrected. |
| FAQ - Answer 3 | 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. Refer to your owner's manual or contact your vehicle's manufacturer for more information. |
| FAQ - Answer 4 | Yes. When ACDelco spark plugs are manufactured, they are pre-gapped to the correct gap specification. |
| FAQ - Answer 5 | 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. |
| FAQ - Answer 6 | 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. |
| FAQ - Answer 7 | 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. |
| FAQ - Answer 8 | Yes, ACDelco has marine spark plugs for many applications. |
| FAQ - Question 1 | Is there a recommended interval for changing my vehicle's spark plugs? |
| FAQ - Question 2 | Should I change all of my vehicle's spark plugs at the same time? |
| FAQ - Question 3 | Does a diesel engine require a different type of plug than a gas engine? |
| FAQ - Question 4 | Are ACDelco spark plugs pre-gapped? |
| FAQ - Question 5 | When I replace my spark plugs, should I also replace my spark plug wires? |
| FAQ - Question 6 | What is pre-ignition and can it damage my engine? |
| FAQ - Question 7 | Can I just clean my spark plugs instead of replacing them? |
| FAQ - Question 8 | Does ACDelco have marine spark plugs? |
| Features & Benefits - Bullet 1 | Iridium composition provides a high melting point and great strength, providing excellent wear resistance and durability |
| Features & Benefits - Bullet 2 | Iridium offers excellent engine idle stability, reliable cold starting, quick acceleration and smooth performance |
| Features & Benefits - Bullet 3 | Three Piece Fired in Suppressor seal meters spark energy for long electrode life, prevents combustion leakage and helps block radio frequencies that can affect vehicle electronics |
| Good Maintenance Practices - Section 1 - Bullet 1 | Grasp the spark plug boot and gently rotate it 90 degrees counterclockwise. Pull the spark plug boot and cable away from the spark plug. If necessary, use a spark plug boot removing tool. DO NOT grab or violently pull spark plug cables. |
| Good Maintenance Practices - Section 1 - Bullet 2 | Brush or air blast dirt away from the well areas before removing spark plugs. CAUTION: Use goggles to protect eyes from debris when applying compressed air to spark plug wells. |
| Good Maintenance Practices - Section 1 - Bullet 3 | Use the correct deep socket size to loosen each spark plug one or two turns. NOTE: To remove spark plugs from aluminum heads, allow the engine to cool. The heat of the engine, in combination with a spark plug that is still hot, may cause the spark plug threads to strip the cylinder head upon removal. |
| Good Maintenance Practices - Section 1 - Bullet 4 | Remove each spark plug and place each one in a tray by cylinder number. This will help identify and relate any unusual condition to the cylinder involved. |
| Good Maintenance Practices - Section 1 - Bullet 5 | Apply dielectric grease into the boot area to reduce the chance of exterior tracking on the buttress tower of the spark plug. This grease also promotes a good heat transfer between the spark terminal screw and boot terminal. |
| Good Maintenance Practices - Section 1 - Bullet 6 | Before installing new spark plugs, use a gap guide to make sure your new spark plugs have the correct gap. NOTE: ACDelco Professional Iridium Spark Plugs are pre-gapped during manufacturing. Never attempt to gap an ACDelco Professional Iridium Spark Plug. You could damage the spark plug. Replace any incorrectly gapped ACDelco Professional Iridium Spark Plugs with plugs that are correctly gapped. |
| Good Maintenance Practices - Section 1 - Bullet 7 | Install spark plugs or glow plugs to the proper torque per the manufacturers' specification. |
| Good Maintenance Practices - Section 1 - Header | Visually inspect spark plugs for signs of wear. Follow these steps for removing spark plugs for inspection, servicing or replacement: |
