14 best spark plugs
Spark plugs are critical components in the automotive industry, particularly related to performance parts and accessories. They play a vital role in the combustion process of an internal combustion engine. Here's what you need to know about spark plugs:
Function: Spark plugs are electrical devices that generate an electrical spark to ignite the air-fuel mixture in the combustion chamber of an internal combustion engine. This ignition initiates the combustion process that powers the engine.
Performance Parts Accessories: Spark plugs are often considered performance parts and accessories because they can have a significant impact on engine performance. High-performance spark plugs are designed to improve combustion efficiency, resulting in better power output and fuel efficiency.
Automotive: Spark plugs are integral to the operation of gasoline and some hybrid engines found in cars, trucks, motorcycles, and other vehicles. They are essential for the engine's overall performance and efficiency.
Types: There are various types of spark plugs available, including:
Copper Core: These are the most basic spark plugs with a copper core center electrode. They provide good conductivity but may have a shorter lifespan compared to other types.
Platinum and Iridium: Platinum and iridium spark plugs have electrodes made of these metals, which provide better durability and performance.They tend to last longer and require less maintenance.
Performance Spark Plugs: Designed for high-performance vehicles, these spark plugs often have unique designs and materials to improve combustion and ignition under extreme conditions.
Maintenance: Spark plugs require periodic maintenance and replacement as they can become fouled or worn over time. Regular maintenance helps ensure optimal engine performance and fuel efficiency.
Gap: The spark plug gap, or the distance between the center and ground electrodes, is crucial for proper ignition. The gap size is specified by the vehicle manufacturer and should be set correctly during installation.
Heat Range: Spark plugs come in different heat ranges to suit various engine designs and operating conditions. Choosing the right heat range is important to prevent pre-ignition or detonation issues.
Upgrades: Many automotive enthusiasts and racers choose to upgrade their spark plugs to improve engine performance. These upgrades can include using colder or hotter plugs, depending on the engine's needs and modifications.
In summary, spark plugs are fundamental components of internal combustion engines, with a direct impact on automotive performance and efficiency. Choosing the right spark plugs and maintaining them properly is essential for the smooth operation of a vehicle's engine, especially in the context of performance parts and accessories for automotive enthusiasts.

Visually inspect spark plugs for signs of wear. Follow these steps for removing spark plugs for inspection, servicing or replacement:
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.
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.
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.
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.
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.
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.
Install spark plugs or glow plugs to the proper torque per the manufacturers’ specification.
ACDelco Spark Plugs
Is there a recommended interval for changing my vehicle’s spark plugs?
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.
Should I change all of my vehicle’s spark plugs at the same time?
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.
Does a diesel engine require a different type of plug than a gas engine?
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.
Are ACDelco spark plugs pre-gapped?
Yes. When ACDelco spark plugs are manufactured, they are pre-gapped to the correct gap specification.
When I replace my spark plugs, should I also replace my spark plug wires?
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.
What is pre-ignition and can it damage my engine?
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.
Can I just clean my spark plugs instead of replacing them?
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.
Does ACDelco have marine spark plugs?
Yes, ACDelco has marine spark plugs for many applications.
