Comparison Insights: Choosing the Right Plug Type

Best Spark Plugs For 2013 Nissan Altima FAQ

Q1: What type of spark plug came standard in the 2013 Nissan Altima 2.5L L4 engine?

The 2013 Nissan Altima 2.5L (L4) typically utilized a long-life Iridium plug from the factory, often specific numbers like NGK DILKAR6A11 or equivalent parts. When selecting replacement spark plugs, choosing a premium material like Iridium or Double Iridium is recommended to maintain optimal OEM performance and service intervals.

Q2: How often should I replace the spark plugs in my 2013 Altima?

For premium iridium spark plugs (the types listed in this guide), the general replacement interval is very long, usually between 80,000 to 120,000 miles. Always check your owner’s manual, but replacing them around the 100,000-mile mark is excellent preventative maintenance for retaining good fuel economy and responsive acceleration.

Q3: What are the common symptoms of bad spark plugs in a 2013 Altima?

Failing or worn spark plugs can cause several noticeable issues, including a rough or vibrating idle, difficulty starting, poor acceleration (hesitation when pressing the gas), and a drop in gas mileage. If the issue is severe, the car might start misfiring, which usually triggers the Check Engine Light (CEL).

Q4: Do I need to replace the coil packs when I change the spark plugs?

It’s not strictly required, but it is highly recommended, especially if your Altima has over 100,000 miles or if you are already experiencing misfires. Old coil packs often fail shortly after new plugs are installed because new plugs demand a higher voltage. Replacing them together (using one of the comprehensive kits reviewed) is a smart way to ensure ignition reliability.

Q5: What is the correct spark plug gap size for the 2013 Nissan Altima 2.5L?

For the 2.5L L4 engine, the standard gap size is typically 0.044 inches. While most modern iridium spark plugs come pre-gapped from the factory, it is always essential to verify this measurement using a feeler gauge before installation, as incorrect gapping can lead to misfires and poor engine efficiency.

Q6: Why are iridium spark plugs better than standard copper plugs?

Iridium offers superior hardness and a much higher melting point than copper. This allows iridium plugs to feature a much finer center electrode (like a needle tip), which concentrates the spark better. This results in more reliable ignition, better resistance to fouling, and a service life that is up to four times longer than standard copper plugs.
