How We Picked These Spark Plugs
You want spark plugs that match your Altima’s engine specs and deliver reliable ignition. We prioritized: compatibility (correct thread, heat range and gap for the 2.5L L4 used in 2013 Altima), core material (iridium/platinum for longer life and stable performance), OEM equivalence (parts that match Nissan part numbers or OE design), user feedback (real-world reliability and fit from reviews), and value (cost per set versus expected lifespan).
We also considered ease of installation and whether a thin-wall spark plug socket is likely required. This selection helps you avoid wasted time, reduced fuel economy, and possible check-engine lights by choosing plugs that actually fit and perform for your car.
9029 Double Iridium Spark Plug
If you want a straightforward replacement that feels like an upgrade, these double iridium plugs are worth a look. You get an iridium center electrode designed for longer life and better ignitability, which translates to easier cold starts, smoother idling, and a bit more pep when you put your foot down.
They’re sold in packs of four so you can refresh all cylinders at once, and the design follows OE specifications (OE# 9029), so fitment for a 2013 Altima L4 2.5L is covered. For everyday driving you’ll notice smoother starts and steadier idle; for longer trips or colder mornings the improved ignitability helps reduce hesitations.
Installation is simple if you’re comfortable with basic hand tools — you can DIY it in your driveway — but they also suit a quick shop install if you prefer. If you want reliability and longer intervals between changes, these plugs are a practical pick.
What People Say
Buyers commonly report improved cold starts, smoother idling and a noticeable improvement in responsiveness after swapping all four plugs. Many appreciate the OE-compatible fit and the longer-life iridium electrodes.

FAQ
Which Spark Plugs Are Best For A 2013 Nissan Altima?
For the common 2.5L L4 2013 Altima you’ll usually want iridium spark plugs because they offer the best balance of longevity and stable ignition; platinum is a good, lower-cost alternative that still outlasts standard copper. Look for parts that list OEM equivalents so you know they match the factory fit and reach — common reference numbers include 9029, DILKAR6A11, LKAR6AIX11, and 91187.
Brands in the market that match these specs include reputable aftermarket options and OE-equivalent designs; before you buy, verify the plug’s thread size, reach, and OEM part number against your engine (and confirm whether your Altima is the 2.5L L4 or a V6, since fitment differs).
How Should You Install And Maintain Spark Plugs On A 2013 Nissan Altima?
When installing, make sure you follow the vehicle service manual: set the plug gap if required (many listings for the 2.5L specify a gap of 0.044″), use a proper spark plug socket and a torque wrench, and tighten to the manufacturer’s recommended torque to avoid damaging the threads. You don’t usually need anti-seize on modern iridium plugs unless the manufacturer specifically advises it, and use dielectric grease on the inside of the coil boot to help seal and prevent sticking (don’t coat the plug electrode).
Replace all plugs at the same time for consistent performance, check coils and boots while you’re in there, and if you’re not comfortable with COP removal or torque specs, have a professional do the job.
What Symptoms Indicate You Need New Spark Plugs And How Can You Avoid Common Issues?
You’ll notice worn plugs through rough idle, misfires, poor throttle response, reduced fuel economy, or a check engine light with codes related to misfire. If you pull a plug and see heavy carbon fouling, melted electrodes, or uneven wear, replace the set and inspect ignition coils. To avoid common problems, buy plugs that explicitly list compatibility with your Altima and match OEM part numbers, use the correct gap and torque during installation, and store replacement plugs in their original packaging until use to avoid contamination. Also be wary of counterfeit parts — buy from sellers with clear fitment info and good reviews, and replace coils or boots if they show cracks or excessive resistance.
Top Customer Picks
When choosing between the 9029 Double Iridium, A-Premium Iridium Platinum (Pack of 4), and A-NAFTULY Double Iridium (4 Pack), you’re usually focused on longevity and consistent ignition performance, plus exact fitment for your 2013 Altima and overall value. Many buyers opt for double-iridium for maximum lifespan and reliable starts, while others pick iridium-platinum when they want a strong performance/price balance and easier replacement costs.
Wrapping Up
Choose the right spark plug for how you drive. If you want the closest thing to OEM quality and long service life, the NGK Laser Iridium pick is the safest bet. If you want strong performance for less money, the NGK Iridium IX or G-Power options perform well.
For tight budgets you can get reliable iridium plugs like the BDFHYK or A-Premium sets that still restore proper ignition and fuel economy. Before you buy, confirm thread size, engine fit, and gap for your 2013 Altima and keep a thin-wall 14mm or specified socket handy if the plug design requires it.
That way you get improved drivability and fewer surprises at routine service intervals.
