Keep your Cube's 1.8L engine running efficiently with the correct aftermarket spark plugs.
- For best results, use Iridium spark plugs from OEM-equivalent brands like NGK or Denso.
- The factory service interval is 105,000 miles; stick to this when using high-quality Iridium plugs.
- Replacement is more complex than on typical 4-cylinder engines because the intake manifold must be removed.
- Always verify the spark plug gap is set to 0.044 inches before installation.
Signs of Failing Spark Plugs in Your Cube
When your spark plugs are worn, your Cube's unique 1.8L engine won't perform as it should. You might notice one or more of these symptoms. 🎬 Watch: 5 alarming signs of bad spark plugs A failing plug can cause the engine to misfire, which means a cylinder isn't working correctly. This can trigger your check engine light.
- Poor Acceleration: The car feels sluggish or slow to respond when you press the gas pedal.
- Rough Idle: You may feel excessive shaking or vibration when the car is stopped but the engine is running.
- Reduced Fuel Economy: You'll find yourself filling up the gas tank more often than usual because the engine isn't burning fuel efficiently.
- Engine Misfires: The engine may stumble or hesitate, and the check engine light might start flashing, which indicates a serious misfire.
- Trouble Starting: Worn plugs can make it harder for the engine to start, especially in cold weather.
Choosing the Right Aftermarket Spark Plugs
For the 2009-2014 Nissan Cube, the factory-installed spark plugs are long-life Iridium units made by NGK. When choosing a replacement, it's best to stick with this technology for reliability and to maintain the original performance. Cheaper copper or standard platinum plugs will wear out much faster and may cause performance issues.
Brand Quality Tiers
Not all aftermarket brands are created equal. For your Nissan, sticking close to the original equipment (OEM) quality is a smart choice.
- Tier 1 (OEM Equivalent): NGK & Denso. NGK is the original supplier for Nissan. Denso is another top-tier Japanese brand known for its quality and is an OEM for many other carmakers like Toyota. Both NGK and Denso Iridium plugs are excellent choices that will restore original performance and last for the full service interval.
- Tier 2 (Quality Aftermarket): Bosch & Champion. These are well-known brands that produce quality Iridium and Platinum spark plugs. While they are a reliable option and may cost less, most Nissan specialists and experienced owners recommend sticking with NGK or Denso for the best compatibility and performance.
Pro Tip: Check the Gap
The correct spark plug gap for the Nissan Cube's 1.8L engine is 0.044 inches. While most Iridium plugs come pre-gapped, it's crucial to verify this with a gap tool before installation. An incorrect gap can lead to misfires and poor performance.
Known Issues, Recalls, or TSBs
Searches of the National Highway Traffic Safety Administration (NHTSA) database and technical service bulletins (TSBs) show no specific recalls or service bulletins related to spark plug failure for the 2009-2014 Nissan Cube. Recalls were issued for unrelated issues, such as a sticking start/stop button on some model years and a fuel filler tube.
Installation Requires Intake Manifold Removal
Unlike many four-cylinder engines where spark plugs are easily accessible, the plugs on the 1.8L engine in the Nissan Cube are located underneath the plastic intake manifold. This manifold must be unbolted and moved out of the way to access the ignition coils and spark plugs. This makes the job more complex and time-consuming for a DIY mechanic and increases the labor cost at a repair shop.

How often should I replace the spark plugs on my Nissan Cube?
The original Iridium spark plugs have a recommended replacement interval of 105,000 miles. If you replace them with high-quality aftermarket Iridium plugs from a brand like NGK or Denso, you can expect a similar lifespan.
Can I use cheaper copper or platinum plugs?
While you technically can, it is not recommended. The ignition system is designed for Iridium plugs. Using a lower-grade plug like copper or single platinum will result in a much shorter service life (around 30,000 miles) and can lead to reduced performance and fuel economy.
What is an ignition coil and should I replace it with the plugs?
An ignition coil is the component that sits on top of each spark plug and transforms the car's 12-volt power into the high voltage needed to create a spark. You do not need to replace the ignition coils unless one has failed, which would typically cause a persistent misfire on a single cylinder (e.g., code P0301 for cylinder 1).
What happens if I don't change my spark plugs?
Ignoring worn spark plugs will lead to a steady decline in engine performance. You'll experience symptoms like a rough idle, poor gas mileage, and sluggish acceleration. In severe cases, a flashing check engine light can indicate that unburned fuel is entering the exhaust, which can damage the expensive catalytic converter.
