Signs of Failing Spark Plugs in Your Element
When spark plugs wear out, they can't create a strong enough spark. This leads to noticeable problems. If you experience any of these issues with your Honda Element, your spark plugs could be the culprit.
- Rough Idle: The engine may shake or vibrate when you're stopped.
- Engine Misfires: You might feel a hesitation or stumble from the engine while driving. This often triggers the Check Engine Light.
- Poor Acceleration: The vehicle may feel sluggish and lack power when you press the gas pedal.
- Reduced Fuel Economy: Worn plugs can cause fuel to be wasted, leading to more frequent trips to the gas station. A bad plug can lower MPG by up to 30%.
- Difficulty Starting: The engine may take longer than usual to turn over and start.
A Common Element-Specific Issue: Oil on Plugs
A very common problem on the Honda Element is a leaking valve cover gasket, specifically the spark plug tube seals. When these seals fail, oil seeps down into the spark plug tubes and fouls the plugs and ignition coils. If you pull out a coil and find oil on it or the spark plug, you will need to replace the valve cover gasket set along with the spark plugs 🎬 See how to replace the valve cover gasket and tube seals. to fix the root cause.
Choosing the Right Aftermarket Spark Plugs
For the 2003-2011 Honda Element, the factory-installed spark plugs were made by either NGK or Denso. These are considered the original equipment (OEM) suppliers. For the best results, it is highly recommended to stick with these two brands.
Brand Tiers for the Honda Element
- Tier 1 (OEM Equivalent): NGK & Denso. These brands provide the best performance and longevity for the Element's K24 engine. The recommended plugs are Iridium-type, such as the NGK Laser Iridium (IZFR6K11) or the Denso Iridium (SKJ20DR-M11). These are designed to last for about 100,000 miles.
- Tier 2 (Alternative): Bosch, Autolite, Champion. These brands offer Iridium and Platinum plugs that will work in your Element, often at a lower price. While they are functional, most Honda specialists and experienced owners prefer to use NGK or Denso for guaranteed compatibility and performance. If choosing one of these, ensure it is an Iridium plug to get the longest life.
Iridium vs. Platinum and Copper
The original plugs are Iridium for a reason. Iridium is an extremely hard material with a very high melting point, which allows for a very fine center electrode. This creates a more focused, powerful spark, leading to better efficiency and a much longer lifespan (over 100,000 miles). Cheaper platinum or copper plugs will have a significantly shorter service life and may not offer the same performance. Given the small price difference over their long life, Iridium plugs are the best value.
Known Issues, Recalls, and Bulletins
There are no specific recalls or Technical Service Bulletins (TSBs) from Honda for the spark plugs on the 2003-2011 Element. The most common related issue is the previously mentioned oil leak from the spark plug tube seals. Some owners have also reported spark plugs becoming seized in the cylinder head if they are not replaced for a very long time, making removal difficult. Using a small amount of anti-seize on the threads of the new plugs can help prevent this, but be careful not to get any on the electrode.

Frequently Asked Questions
How often should I change the spark plugs on my Element?
If you use the recommended NGK or Denso Iridium spark plugs, the replacement interval is every 100,000 to 105,000 miles. If you use lower-quality platinum or copper plugs, you will need to change them much more frequently, possibly every 30,000 miles.
Do I need to gap the new spark plugs?
No. The recommended NGK and Denso Iridium plugs come pre-gapped from the factory to the correct specification (around 0.044 inches or 1.1mm). You should not attempt to gap them, as the fine Iridium electrode can be easily damaged. Just check that the tip isn't bent or crushed from shipping.
Is replacing the spark plugs a DIY job?
Yes, for most people this is a very straightforward and easy DIY job. It requires basic tools like a socket wrench, a 10mm socket, and a 5/8" spark plug socket with an extension. The job can typically be completed in under an hour.
