Best Spark Plugs For Nissan Altima Reviewed

Just as you replace your car battery occasionally, you also need to replace the spark plugs. The trouble can be finding the best spark plugs for Nissan Altima.

In our complete review, we look at Nissan Altima spark plugs, among other models, so you can replace the worn-out, fouled plugs currently in your engine.

Choosing Quality Spark Plugs for Your Nissan Altima

Vehicle Compatibility

If you need the best spark plugs for a 2005 Nissan Altima, you don't want to search the spark plugs for a 2013 Nissan Altima. Instead, you look for compatibility based on the make, model, and year of your vehicle. Plus, the spark plugs must work with the engine you have.

Insulation & Heat Range

The spark plug insulator type showcases the firing tip. It tells you how much of the central electrode protrudes from the threaded plug shell. Additionally, you want to know the heat range, whether it is considered a hot or cold spark plug, as each one serves a unique purpose.

Gap & Thread Size

The spark plug gap must be correct for the engine to operate correctly. Most spark plugs come pre-gapped as per the manufacturer's specifications, but you should always double-check it with a spark plug gap tool. Plus, your engine requires a specific thread size for the plugs to fit properly.

Spark Plug Type

You have three main types of spark plugs to choose from, but what is the best type of spark plug to use on a Nissan Altima? The copper plug is the cheapest, but it doesn't provide as much performance. If you don't mind spending more, you should opt for either platinum or iridium plugs for more performance and a longer service life.

Change Intervals & Life Expectancy

Some plugs need to be changed every 30,000 miles. If you don't mind doing tune-ups that often, you could choose these and save some money upfront. However, higher-quality spark plugs will go up to 100,000 miles, thereby reducing how often you need to do a tune-up to your Nissan Altima.

Warranty

The majority of spark plug companies offer a one-year warranty on the equipment. However, there are some that provide more protection and others that offer less. You have to determine how much of a guarantee you need. Just remember to read the customer reviews to see how others feel about the quality.

Price

If you choose a cheap set of spark plugs, they aren't going to last long. Sure, you save money today, but how soon will you be changing the plugs again? By purchasing better plugs with a longer service life, you might have to pay more right now, but the price-per-mile might actually be lower, which reduces your overall tune-up costs in the future.

The best part about these spark plugs for a 2014 Nissan Altima is the warranty. Even though they are low-cost, you still receive a one-year warranty, which is longer than many top brands. However, some people have struggled to get the plugs with the appropriate gap. You want to double check it when they arrive and use your gap tool as needed.

If you want a low-cost option while looking for spark plugs for a 2015 Nissan Altima or Titan, you are in luck.

5. NGK LFR5A-11

You can find not only the best spark plugs for a Nissan Sentra, but also the Maxima, especially if you are simply looking for a copper option. These 2005 Nissan Altima 3.5 spark plugs contain NGK's V-Power technology for more economical performance, even though they aren't constructed from platinum or iridium. That's because they contain V-Groove technology. 

With this advanced setup, you can count on better ignitability, lower voltage requirements, and strong anti-fouling characteristics. Plus, acceleration and fuel economy should be improved. The V-Power plugs are also durable and remain protected from chemical or electrical wear, allowing you to go longer between replacements. The heat isn't absorbed by the electrode itself, as with some other plugs, allowing for a more complete burn.

As with the other NGK options, these plugs only come with a 60-day warranty, which upsets some customers. However, it seems rare for anything to go wrong with the V-Power plugs. Additionally, you will need to spend a little more than you might have planned on copper plugs, but these offer similar performance to platinum or iridium designs, so don't turn away simply based on the price. You can use these plugs for your Altima, Titan, Quest, or Maxima.
