Iridium Spark Plugs for Nissan Sentra, Frontier & Titan (Set of 6) — OE 22401-5M015

Iridium Spark Plugs for Nissan Sentra, Frontier & Titan — Set of 6

If you've been searching for a solid set of Nissan Sentra Frontier Titan spark plugs, this six-pack is built to get your engine firing clean again without any surprises. These are iridium plugs, cross-referenced to OE part number 22401-5M015 (also listed as PLFR5A11 / 224015M015 / PLFR5A-11), and they're made as a direct bolt-in replacement — no drilling, no adapters, no fuss. Pull the old plugs, thread these in, torque them down, and you're done.

A Quick, Important Fitment Correction

We want to be upfront about something. This listing used to reference the 350Z and Altima with the VQ35DE engine, and that was wrong — a copy-paste mistake carried over from a similar listing. The manufacturer's actual fitment data, which is more specific and more reliable than that old title text, points to three vehicles only:

• Nissan Sentra — 2000 to 2006
• Nissan Frontier — 2005 to 2010
• Nissan Titan — 2004 to 2006

If you drive a 350Z or an Altima with the VQ35DE, these are not your plugs, and we'd rather tell you that now than have you order the wrong part. If your vehicle is a Sentra, Frontier, or Titan in the years above, you're in the right place. Still not 100% sure your model and trim line up? Send us your VIN or engine code through our request a part page before you order and we'll confirm fitment for you — it takes two minutes and saves everyone a headache.

Why Iridium Instead of Standard Copper Plugs

Iridium spark plugs use a much finer center electrode than a standard copper plug — often a fraction of the diameter. That smaller tip needs less voltage to fire a spark, which tends to translate into a cleaner, more consistent burn and steadier idle. Iridium is also a hard, heat-resistant metal, so these plugs typically hold up longer under normal driving conditions than a basic copper plug, meaning fewer trips back under the hood to swap them out. None of that is marketing fluff — it's just how the metal behaves compared to copper, and it's the whole reason iridium plugs cost a bit more up front but tend to pay you back in longevity.

What You're Getting

This is a complete set of six spark plugs — enough for a full tune-up on your Sentra, Frontier, or Titan in one go, rather than buying plugs one at a time and hoping you remembered the right count. Each plug is built as a direct-fit aftermarket replacement, so your factory gap, thread, and reach specs are already accounted for. No machining, no trimming, no "close enough" fitment.

Installing Them

Swapping spark plugs is one of those jobs most people with basic tools can knock out in a driveway on a Saturday morning. Let the engine cool down first — a hot engine block will make the plugs harder to remove and can damage the threads if you're not careful. Pull the ignition coil or wire off one cylinder at a time so you don't mix up the firing order, then use a spark plug socket to back the old plug out. Check the gap on the new plug against your vehicle's factory spec before installing (yes, even pre-gapped plugs are worth double-checking), thread it in by hand until it seats, and finish with a torque wrench rather than muscle — overtightening an iridium plug is a common way to crack the porcelain insulator or damage the threads in the cylinder head. If you're not confident doing this yourself, any general repair shop can install a set like this in well under an hour.

A quick word on spark plug basics for anyone newer to this: a spark plug's job is to ignite the compressed air-fuel mixture in the cylinder at precisely the right moment, and small differences in electrode material and design genuinely do affect how efficiently that happens. If you want a deeper technical rundown on how spark plugs work, Wikipedia's spark plug article is a solid, neutral reference.
