ACDelco Spark Plugs
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.

User questions & answers
| Question: | How many plugs in your "4 pack |
| Answer: | Depends on which seller they come from. I had one order from Amazon.com, and the other Shipped by AIMS Auto. The Amazon order only had 1 plug, the other order had all 4. They were only ordered 10 minutes apart and arrived 1 day apart. Since the item was then sold out, Amazon refunded my order and let me keep the single plug. Sucks because I had to buy 3 more at AutoZone for $7.99/ea |
| Question: | Will these work on my 2006 GMC |

| Question: | How many plugs in your "4 pack |
| Answer: | I had "store pickup" for myself as it was only a few blocks away. But, when I asked for my 2 four packs ( I was assuming that I was ordering two boxes with 4 spark plugs in each box). Which would be a quantity of 2 of the item number purchased which by the only picture representing the item being purchased clearly has 4 (Four) spark plugs in a row The person behind the counter said...oh no, this order is for two (2) spark plugs. The item number is per: Each...meaning 1 (One). I showed them my online order with everything as just described and they had no choice but to give me 8 spark plugs. They did not want to, but they did. |
| Question: | Ad is for a four pack. Does it come with four plugs or one? Bad reviews indicate customers only got one plug |
| Answer: | I got 4 plugs in one box. So I ordered two boxes for my 5.3L. I got them installed and so they are working well! |

ACDelco Spark Plugs
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.

User questions & answers
| Question: | Are these $3 rebate per spark plug? Or $3 per order |
| Answer: | Yes. It fit my 1990 Crx dx |
| Question: | Do i need anti-seize lubricant with these spark plugs |
| Answer: | Hello Omar, No. This application has an ignition system with a coil on plug design, which does not require a wire set. Thank you for considering NGK products for your ignition replacement needs. |
| Question: | What are theses pre-gapped to |
| Answer: | Yes they are - just be sure to replace one at a time, and pay attention to the lengths of each wire. This is a super easy job, just pull off the old one, then replace it with the new one, and make sure the wires are snug down by hearing a 'snap' onto the spark plug. |
| Question: | What size socket do I need to install these |
| Answer: | I leave mine outside in all kinds of weather, including rain and snow, and don't have any problems. |

| Answer: | Yes, the NGK (9988) HE53 Spark Plug Wire Set should fit your 1991 Honda Civic LX Sedan without any problems, since it has similar engine displacement and layout as my '91 Honda CRX. I've had this set for several years now and they still work and fit well like the OEM, unlike the previous Bosch set that kept slipping off the spark plugs. Hope this helps. |
