14 best iridium spark plugs

Iridium spark plugs are a type of spark plug commonly used in automotive engines.They are designed to improve engine performance, fuel efficiency, and longevity compared to traditional copper or platinum spark plugs. Here are some key features and benefits of iridium spark plugs:

  1. Material: Iridium spark plugs have a center electrode made of iridium, a dense and durable metal. This material is chosen for its high melting point and excellent conductivity.

  2. Small Electrode Diameter: Iridium spark plugs have a very small and fine center electrode, which allows for a more precise spark and better ignition of the air-fuel mixture in the engine's cylinders. This can result in improved combustion and engine efficiency.

  3. Longevity: Iridium spark plugs have a longer service life compared to traditional spark plugs. Their durable electrode material resists wear and erosion, meaning they don't need to be replaced as often.

  4. Improved Cold Starts: Iridium spark plugs provide reliable ignition even in cold weather conditions, ensuring that the engine starts smoothly.

  5. Better Fuel Efficiency: The precise spark generated by iridium spark plugs can lead to more efficient combustion, which can result in better fuel economy for the vehicle.

  6. Reduced Emissions: Improved combustion also means reduced emissions of harmful pollutants from the vehicle's exhaust, contributing to a cleaner and more environmentally friendly operation.

  7. Compatibility: Iridium spark plugs are available for a wide range of vehicle makes and models, making them a suitable choice for many different types of engines.

  8. Maintenance: Due to their extended lifespan, iridium spark plugs require less frequent replacement, reducing the overall maintenance costs of a vehicle.

  9. Performance: Iridium spark plugs are often chosen by enthusiasts and performance-oriented drivers for their ability to provide consistent and efficient spark, which can enhance engine performance.

In summary, iridium spark plugs are a popular choice for modern vehicles due to their durability, improved combustion, fuel efficiency, and compatibility with a wide range of engine types. They are a worthwhile investment for those looking to optimize their vehicle's performance and reduce maintenance costs.

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: What is the difference between iridium plugs and platinum plugs
Answer: They fit my 2011 Avalanche with the 5.3 fine.
Question: Did you use it for chevy tahoe or Suburban 5.3 (2007-2014) ? and do you need to adjust the Gap before install it
Answer: Generally these plugs are OEM replacements for several GM and Chevy vehicles. Without an old plug number to cross reference I cannot tell you with any certainty if this particular plug would fit your application.
Question: Will these plugs fit my Chevy Suburban
Answer: Real. Put them in my Silverado truck a year ago and they are doing a great job.
Question: What is the socket size
Answer: Specs get updated all the time. I have learned that the hard way recently. My '03 Escalade owners manual suggested Platinum AC Delco or NGK Spark plugs gapped at 0.060. When I received the NGK spark plugs they were set at 0.045 if I recall correctly. I went ahead and gapped them at 0.060 as suggested by the owners manual, I didn't noticed an improvement in acceleration or MPG. I have now learned that GM now recommends the Iridium spark plugs gapped at 0.040 for my SUV which is way different than what it originally came with. ***Notice: The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used. ***

User questions & answers

Question: Would this fit a 2018 Hyundai elantra
Answer: Iridium is a harder metal than platinum. With the harder metal, the iridium plug will last longer but with that comes a down side. The metal is not the best heat conductor. The best being Silver, then copper, then platinum, iridium and finally nickle. Your best bet is to stay with what the manufacturer recommends. Then again, if you have a vehicle that changing the plugs is a nightmare, it may be a good idea to go with a plug that will last upwards 100,000 miles. If you change your plugs every 15,000 or 20,000, then copper might be a great option as well.

Question: Would this fit 2010 Ford Expedition
Answer: This is for one spark plug. If the price is less than $10, it is for one. I got four for $24 but they are worth it. 100,000 plus miles.
Question: I have a old lincoln car it's 2014 year Navigator 5.4L V8,is it work
Answer: In my experience, I replace the spark plugs about every 60000 miles, but most manufacturers would recommend that spark plugs be replaced every 20000 miles. This will depend on driving conditions. No matter which brand or type spark plug you get, you should be replacing at the manufacturer's recommended intervals. One of the reasons what makes these spark plugs better than most, is the consistency of the spark over the life of the spark plug. And in my opinion, better reliability and less chance of failure.
Question: This is fits on 05 f150 5.4l
Answer: Go to the Bosch web site to find your plug number.

User questions & answers

Question: Is this 6r12, if so why does it not say so
Answer: I never trust "Pre-gapped"; always do your own checking. Better safe than sorry!
Question: Do you get 1 or 2 spark plugs in this price
Answer: Product description says Pack of 1.
Question: Should I gap to my owners manual spec or are they designed to work with the smaller pre-gap they came with
Answer: Your question is out of my reach but I can tell you that on my Hyundai Sonata 2002 this plugs just revived it to a near new condition . I've got power I didn't know it had.
Question: They come pre gapped to what spec
Answer: I received my NGK plugs with a .042 gap. My Toyota Corolla Owners manual say's .043 for a gap setting. Advance AutoParts.com has post for this plug a gap setting of .044. Since the settings were not correct and technically the plugs should have came with the correct gap Amazon made good on the purchase. So now I need to possibly reorder. Ebay has these plugs, 4 for 14.99. Maybe that's why.

User questions & answers

Question: Are they already gapped to oem specs
Answer: NEVER depend on the gap of a sparkplug to be correct.
Question: Will these spark plugs fit a 2009 Nissan Maxima
Answer: correct part is ILZKR7B-11S
Question: Are these iridium spark plugs
Answer: Without examining the plugs "up close and personal," I would not be able to offer an opinion. Some things to watch for are: The lettering on the insulator must be centered. Counterfeit plugs have the lettering closer to the top. Google counterfeit NGK plugs for pictures. Measure the resistance with an ohm meter. All plugs should be really close to 5000 ohms. Look for a small circular disc welded onto the inside of the ground electrode. This is platinum on a genuine plug. Counterfeit plugs dont have the disc. Check the gap. Genuine plugs come pre-gapped. Counterfeit plugs all have different gap measurements.

Iridium

Iridium’s long lasting high durability platinum makes them a great competitor for those looking for a reliable spark plug. Iridium's high melting point is perfect for modern vehicles that run higher-temperature engines. Iridium spark plugs deliver more complete combustion, higher fuel efficiency, and longevity.

Platinum

Platinum spark plugs feature a small center electrode that helps reduce the amount of voltage required to generate a spark; platinum spark plugs have proved to have a longer lifespan and overall better combustion. Platinum spark plugs also include a single platinum spark plug and a double platinum spark plug.

Copper

Copper is highly conductive and resilient to heat and one of the oldest commonly installed spark plugs. Copper is a soft metal alloy that generally requires more voltage and cannot withstand pressure and time like other metal alloys.

Product Features

ENA Platinum plugs are designed to meet OEM quality and durability standards. The Platinum series features vehicle grade ceramic and fine wire center electrodes which provides OE performance at high efficiency for longer lasting spark plugs. The platinum Center electrode tip wears less than a standard spark plug, maintaining gap setting for longer periods. At 3x stronger than Copper plugs, Platinum spark plugs retain excellent wear resistance while lasting 25% longer, providing you with peace of mind.

  • Reliable cold start
  • Heat and pressure resistant
  • Rust proof
  • Excellent Long Span
  • Excellent current conductivity
  • Copper core electrode provides superior thermal conductivity
  • Unique ribbed insulator reduces flashover and decreases voltage loss

Strength

Our Platinum plugs are 3x stronger than Copper spark plugs which greatly reduces electrode wear and lasts 25% longer than standard spark plugs. The hard metal alloy has a high melting point which allows it to generate more heat and reduce spark plug deposit and debris buildup. Longevity is the best feature of platinum spark plugs. The high grade ceramic allows for stronger insulation and threads to prevent damage to cylinders. The ultra-fine wire requires less voltage to fire up.

Testing

Hours of testing have gone into our spark plugs to ensure that they pass extensive testing procedures and quality checks to ensure perfect fit and performance.
