![]() ![]() Iridium spark plugs are good value for your money. Spark plugs made from this metal have the capacity to endure extreme internal pressure, also their higher thermal resistance helps them to last 25% longer than other spark plugs. ![]() Iridium is six times harder and eight times stronger than platinum. After installing these plugs you won’t have to think about replacing them for a long time. They are also known as long-life spark plugs for their robustness and strength. Replace your dirty, fouled spark plugs with new ACDelco spark plugs.Iridium spark plugs are the most popular and reliable spark plugs in the automotive market. These conditions severely affect spark plug performance. Dirty, fouled spark plugs may also have broken, chipped insulator tips, worn electrodes, or worn or missing side wires. Cleaning your old spark plugs is not recommended. Q: Can I just clean my spark plugs instead of replacing them?Ī: No. 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. 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. Pre-ignition can cause serious damage to your engine. Q: What is pre-ignition and can it damage my engine?Ī: Yes. Refer to your vehicle owner’s manual or contact the manufacturer for more information.Ī: Certain engine conditions can cause oil, powder, and carbon to collect on the spark plug causing a misfire. Q: When I replace my spark plugs, should I also replace my spark plug wires?Ī: Not always, but you should inspect your spark plug wires for wear when replacing your spark plugs. When ACDelco spark plugs are developed, they are pre-gapped to the correct gap specification. However, 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.Ī: Yes. All of the spark plugs should be changed if it is the scheduled time for spark plug replacement. Q: Should I change all of my vehicle’s spark plugs at the same time?Ī: Yes. However, this is not the cure for poor engine performance caused by worn mechanical components, improper fuel delivery, worn ignition parts, or other engine performance issues. Replacing old spark plugs may temporarily improve poor engine performance due to reduced demand on the ignition system. However, spark plugs may not be the only factor impacting performance. Q: Can changing my spark plugs improve my engine’s performance?Ī: Yes. Refer to your owner’s manual or contact your vehicle’s manufacturer for more information. It depends on what type of spark plug your vehicle requires. Q: Should I change my spark plugs every 30,000 kilometers?Ī: No. Install spark plugs or glow plugs to the proper torque per the manufacturers’ specification.Replace the incorrectly gapped ACDelco Iridium Spark Plug with one that is correctly gapped. Never attempt to gap an ACDelco Iridium Spark Plug. NOTE: ACDelco Iridium Spark Plugs are pre-gapped during manufacturing. Before installing new spark plugs, use a gap guide to make sure your new spark plugs have the correct gap.This grease also promotes a good heat transfer between the spark terminal screw and boot terminal. Apply dielectric grease into the boot area to reduce the chance of exterior tracking on the buttress tower of the spark plug.This will help identify and relate any unusual condition to the cylinder involved. Remove each spark plug and place each one in a tray by cylinder number.CAUTION: Use goggles to protect eyes from dirt when applying compressed air to spark plug wells. Brush or air blast dirt away from the well areas before removing spark plugs.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. NOTE: To remove spark plugs from aluminum heads, allow the engine to cool.Use the correct deep socket size to loosen each spark plug one or two turns.DO NOT grab or violently pull spark plug cables. If necessary, use spark plug boot removing tool. Pull the spark plug boot and cable away from the spark plug. Grasp the spark plug boot and gently rotate it 90 degrees counterclockwise.Follow these steps for removing spark plugs for inspection, servicing or replacement: Visually inspect spark plugs for signs of wear. ![]()
