6 Best Spark Plugs For Nissan Sentra: Unleash the Power and Efficiency

Spark plugs generate a bolt of electricity that ignites the fuel and air mixture in your Nissan Sentra’s combustion chamber. As such, your car will not start without them. But overtime mileage and age take their toll on the spark plugs.

And when this happens, replacing them is pretty much the only thing you can do to get your engine firing again. So what are the best spark plugs for Nissan Sentra to replace your worn-out plugs with?

As an automotive enthusiast with a passion for tinkering with cars, I embarked on a hands-on journey to test a range of spark plugs tailored for the Nissan Sentra. Through real-world testing and meticulous analysis, I identified six exceptional spark plugs that truly stood out as top performers.

Best Spark Plugs For Nissan Sentra

Types of Spark Plugs

But before we review the six, let’s start with some basics, like the types of spark plugs available and their characteristics.

You will find 4 main types of spark plugs in the market: copper, single and double platinum, and iridium plugs.

Copper Spark Plugs

Let’s start with the classic Copper Spark Plugs, which have been around for ages and remain widely used. Drawing from my experience working on Nissan Sentra engines, I can attest to their economical nature. These plugs boast a copper core with a nickel alloy electrode, featuring a 2.5 mm diameter. Over the years, I’ve observed their distinctive ability to handle higher current loads compared to other spark plugs.

Also, they have a shorter lifespan and will generally need replacing after about 20,000 miles. They are, however, economical and more widely used, especially in order cars.

Single Platinum plugs

Single platinum plugs are similar to copper plugs but use a platinum disc instead of a nickel alloy. Platinum is harder than nickel and can better withstand the high heat and pressure spark plugs are exposed to. 

Therefore these plugs can last up to 60,000 miles and some up to 100,000 miles. One downside of these plugs is that since platinum is less conductive than copper, their performance is lower compared to that of copper plugs.

Double Platinum plugs

A double platinum plug has platinum discs on both the center of the electrode and the ground. These are less common and were designed mainly for waste spark systems. In these systems, the compression stroke of the spark plug jumps from the center electrode to the ground one.

Iridium Spark Plugs

Iridium is harder and stronger than platinum and thus lasts longer. These types of plugs are the most durable and longest-running. However, they are not as conductive as copper plugs. Also, iridium is a costly metal, and thus these spark plugs cost more. 

However, they typically have thinner center electrodes of about 0.4mm, which means they require less voltage to generate a spark. Thus the only major downside of these spark plugs is their cost.

Glow Plugs (Diesel engines):

If your Nissan Sentra has a diesel engine, it will use glow plugs instead of spark plugs. Glow plugs preheat the combustion chamber in diesel engines to facilitate cold starts.

How do I know if your  Nissan Sentra spark plugs need replacing?

  • Slow or Sluggish acceleration: If your Nissan has trouble accelerating and feels sluggish, it may be due to bad spark plugs. This is usually caused by the conductive metal becoming worn out and less effective.
  • Bad fuel efficiency: When a spark plug is worn out, the gap between the electrodes degrades. And when it becomes too large or small, it will not properly ignite the fuel and air mixture. This results in the engine having to draw in more fuel when you press on the accelerator. And the results are more trips to the gas pump.
  • A misfiring engine: A misfiring engine can result from several issues with the ignition system, one of which are worn-out spark plugs.
  • Difficulty starting the car: A worn-out spark plug will not ignite the fuel and air mixture efficiently, resulting in difficulties starting your car.
  • Check engine light is on: The check engine light is usually the first sign of something wrong with the engine, and one of them can be a worn-out spark plug.

How often should you replace spark plugs on a Nissan Sentra

The recommended interval of changing spark plugs on a Nissan Sentra is after every 30,000 miles. However, this may be higher or lower depending on your specific Sentra model and year of manufacture. Ideally, you want to check your owner’s manual for the exact interval.

How To Choose The Right Aftermarket Spark Plugs For Your Nissan Sentra

What should you consider when shopping for replacement spark plugs for your Nisan Sentra? There are a couple of things to consider, the main ones being. 


The first and perhaps most important is compatibility; the plugs you choose need to be compatible with your specific Nissan Sentra model. Spark plugs will have the cars they fit listed on their descriptions. However, most NGK spark plugs should be compatible with the Nissan Sentra. 

Heat Range

Cold and hot spark plugs can be differentiated by their length. Hot ones tend to be longer than cold ones. For the Nissan Sentra, either of the two will do. Cold spark plugs are designed for high-performance vehicles, while hot plugs are for low-application engines. Thus host plugs should be sufficient for the Nissan Sentra.

Electrode Design

The electrode design influences the spark plug’s ability to generate a strong and consistent spark. Single and multi-ground electrode designs are common. Multi-ground electrodes offer better performance and longevity, making them a preferred choice for many Nissan Sentra owners.

Gap Size

The distance between the ground and center electrodes is called the spark plug gap. Different engines require different gaps. Consult your owner’s manual for the right gap for your engine. Also, go for spark plugs that can be gapped so that, if need be, you can adjust the gap on your new plugs to fit your engine.


The material used to make the spark plug’s center electrode will impact its quality and performance. Traditional copper plugs offer better conductivity but do not last long. Platinum is a more durable material and will last longer. Iridium plugs have a higher lifespan than copper and platinum.

The Brand

Some manufacturers have a better reputation for making spark plugs than others. NGK, for example, has some of the best spark plugs. Thus they should be a good fit for your Sentra. Bosch is another brand known for its quality plugs.

Proper Installation Procedures

When installing new spark plugs, there are a couple of things to take note of.

  • Ensure it has the proper gap: The first thing is to ensure the gap of the spark plugs is the right one for your engine. You can use a gap gauge or a feeler gauge to check the gap on the spark plugs.
  • Set the new plug: Now set the plug by hand and ensure you turn it clockwise in two full turns. Once the plug is snug, use a torque wrench to tighten it. The washer of the plug should be pressed against the mounting surface.
  • Replace the plastic boot: It is essential to replace the plastic boot of the plug and ensure it clicks into place. You may have to apply a coat of dielectric grease on the boot to ensure it is easy to remove.

Recommended maintenance intervals

For copper or platinum plugs, you should have them checked every 30,000 to 50000 miles. For iridium plugs, you can do this after 60,000 to 150,000 miles.
