Spark Plug Replacement Guide for the 2016-2024 Nissan Murano
Keep your Murano's 3.5L V6 engine running smoothly by understanding when and how to replace your spark plugs.
- The factory service interval for spark plug replacement is 105,000 miles.
- Use high-quality Iridium spark plugs from an OEM brand like NGK for best results.
- Replacement is an advanced job because the intake manifold must be removed to access the three rear spark plugs.
- To save on future labor costs, consider replacing the three rear ignition coils at the same time as the spark plugs.
Is Your Murano Telling You It's Time for New Spark Plugs?
Worn-out spark plugs can't create the strong spark your engine needs. This leads to noticeable performance problems. If you experience any of these symptoms, your spark plugs could be the culprit.
- Rough Idle: Your Murano may shake or vibrate more than usual when stopped at a light. This is often caused by an engine misfire at low speeds.
- Poor Acceleration: If your vehicle feels sluggish or slow to respond when you press the gas pedal, failing spark plugs might be to blame.
- Reduced Fuel Economy: A weak spark leads to incomplete fuel combustion, meaning your engine wastes gas and you'll find yourself at the pump more often.
- Engine Misfires: You might feel a jerking or stumbling sensation during acceleration. A flashing check engine light is a serious sign of a misfire that could damage other components.
- Difficulty Starting: A weak or inconsistent spark can make it harder for the engine to start, especially when cold.
Choosing the Right Aftermarket Spark Plugs for Your Murano
For the 3.5L V6 engine in the 2016-2024 Murano, the choice of spark plug material is important. The original factory plugs are long-life Iridium plugs, and it is highly recommended to use the same type for replacement to maintain performance and longevity.
Brand Quality Assessment
Not all spark plugs are created equal. While several brands are available, your Murano's ignition system was designed with a specific type in mind.
- NGK: NGK is the Original Equipment Manufacturer (OEM) for many Nissan vehicles, including the Murano. Choosing NGK Iridium plugs is the safest and most recommended option, as it restores the vehicle to its original factory performance and quality.
- Bosch: Bosch is a well-known brand that produces quality spark plugs. While they offer compatible Iridium plugs for the Murano, they are generally considered a top choice for European vehicles. Some Nissan owners have used them successfully, but the general consensus leans toward sticking with the OEM brand.
- Champion: Champion is another established brand offering Iridium plugs that fit the Murano. They are a viable aftermarket alternative, but like Bosch, they are not the original equipment brand for Nissan.
Pro Tip: Stick with Iridium
Your Murano came with Iridium spark plugs for a reason: they offer the best combination of performance and longevity, lasting up to 105,000 miles. While cheaper Platinum or Copper plugs might be available, using them can lead to reduced performance and a much shorter service life, requiring more frequent changes.
The Challenge of Replacing Murano Spark Plugs
Replacing the spark plugs on the Murano's V6 engine is not a simple task. The front three plugs are easy to access, but the rear three are located underneath the upper intake manifold. To access them, the entire manifold must be removed. 🎬 Watch this detailed walkthrough of the intake manifold removal process. This makes the job significantly more complex and time-consuming.
DIY Warning: Advanced Skill Required
This is not a beginner-friendly job. It requires removing multiple components, hoses, and electrical connectors. If you are not an experienced DIY mechanic with the right tools, it is recommended to have this service performed by a professional. Mistakes during reassembly, like a vacuum leak, can cause significant engine problems.
