Comparison Insights for Nissan Altima Spark Plugs

When choosing among these options, the main decision revolves around material and whether you need ignition coils too.

If your Altima has over 100,000 miles and is idling roughly, you should strongly consider purchasing one of the full coil pack and spark plug kits (like Product 1, 5, 6, 8, or 9). This guarantees a refreshed ignition system and often saves money compared to buying the parts separately.

For maximum durability and the longest replacement interval (over 100,000 miles), stick with Double Iridium plugs (Product 2, 8, 10). These offer the best resistance to gap erosion.

If brand trust is your top priority, NGK (Products 3 and 7) are reliable choices. The NGK Laser Iridium (Product 7) is especially favored for 2013+ Altima models as it often meets or exceeds OE specifications for longevity.

The kits that include the UF549 coil pack and 9029 plug (such as Product 1, 6, and 8) offer the most common compatibility for 2.5L Altimas built after 2007.

Final Verdict

Making the right choice depends entirely on your Altima’s age and current condition:

The Best All-In-One Value: Go with the UF549 Ignition Coil Packs & 9029 Double Iridium Spark Plug kit (Product 8). It combines the convenience of replacing old coils with the superior longevity of double iridium plugs, giving you total peace of mind for years to come.

The Best Longevity Upgrade (Plugs Only): For newer 2013-2018 Altima owners, the 4 pc NGK Laser Iridium Spark Plugs (Product 7) are the premium choice. They provide proven OE quality and unparalleled long-term reliability.

The Best Budget Reliability (Plugs Only): If your coils are fine, the A-Premium Double Iridium Spark Plugs (Product 10) offers outstanding longevity (up to 120k miles) at a very competitive price point, specific to later Altima generations.

Comprehensive FAQ About Best Spark Plugs For Nissan Altima

What is the recommended service interval for Nissan Altima spark plugs?

For most modern (2007+) Nissan Altima 2.5L engines running iridium or double iridium spark plugs, the recommended replacement interval is between 80,000 and 105,000 miles. Always consult your Altima’s owner’s manual, but generally, premium iridium plugs offer the longest lifespan.

Should I replace my ignition coils when I replace my spark plugs?

It’s often highly recommended, especially if your Altima has over 100,000 miles or if you are experiencing symptoms like a rough idle, engine misfire, or decreased power. Ignition coils degrade over time due to heat and voltage stress. Many products reviewed above offer convenient coil pack and spark plug kits for this reason.

What is the difference between Iridium and Double Iridium spark plugs?

Iridium plugs feature an iridium center electrode, providing high durability and performance. Double Iridium spark plugs use iridium on both the center and ground electrodes. This dual application minimizes gap erosion significantly, resulting in a more stable, longer-lasting spark and extending the service life to 100,000+ miles.

Do I need to gap my new spark plugs before installation in my Altima?

While many premium iridium spark plugs (like NGK Laser Iridium) come pre-gapped specifically for your Nissan Altima engine, it is always a good practice to confirm the gap setting using a feeler gauge. Nissan Altima 2.5L engines typically require a precise gap, often around 0.044 inches. Never try to manually adjust the gap on fine-wire iridium plugs, as you could damage the delicate tip; only check for accuracy.

How do I know if my current Altima spark plugs are failing?

Common symptoms of failing spark plugs include engine hesitation or stumbling during acceleration, a noticeably rough or unsteady idle, a decrease in your overall gas mileage (MPG), or difficulty starting the car. In severe cases, the “Check Engine” light may illuminate, indicating a cylinder misfire.

Are aftermarket spark plug kits reliable for my Nissan Altima?

Yes, many high-quality aftermarket kits that use OE equivalent reference numbers (like UF549 for coils and 9029 or DILKAR6A11 for plugs) are highly reliable and offer exceptional value. While genuine Nissan parts guarantee a perfect match, the best spark plugs for your Nissan Altima often come from reputable third-party brands like NGK, Denso, or established aftermarket suppliers reviewed here, provided they use premium materials like iridium.
