FAQ

Which Spark Plugs Should You Choose For A 2004 Nissan Titan?

You’ll want plugs that match the 5.6L V8 requirements and the engine’s reach and thread size; common good options are iridium plugs for longevity and stable ignition or platinum for a midground between life and cost. The NGK Iridium IX LFR5AIX-11 is a proven OEM-quality choice if you want top reliability, the SYKRSS compatible iridium pack is a value-oriented iridium alternative, and vehicle-specific platinum options from trusted brands give decent performance for everyday driving.

Make sure the part you buy explicitly lists fitment for a 2004 Titan 5.6L V8 or the equivalent PLFR5A-11/LFR5AIX-11 specification and remember this V8 needs 8 spark plugs total.

How Should You Install And Care For Spark Plugs In Your Titan?

You should gap each plug to your vehicle’s specification and verify the exact value in your service manual; many 5.6L V8 listings show around 0.043–0.044 inches but you must confirm for your engine. Use a clean 5/8 in socket and a torque wrench and tighten to the factory torque spec rather than guessing, avoid over‑tightening, and clean the plug holes before installation.

Do not apply anti‑seize to factory-coated iridium plugs unless the manufacturer recommends it; instead lightly coat the inside of the coil boot with dielectric grease to help prevent moisture and boots sticking. Replace all plugs at once for even performance and inspect ignition coils and boot condition while you’re in there so you don’t swap in new plugs and leave a failing coil behind.

Will Upgrading To Iridium Or Platinum Improve Performance And What Are Common Misconceptions?

Upgrading to iridium typically gives you longer service life and a more consistent spark compared with copper or standard plugs, which can help with smooth idling, starting, and stable combustion especially on stock or lightly modified engines; don’t expect dramatic horsepower gains—improvements are usually subtle in drivability and fuel usage. A common misconception is that a larger gap always yields more power; in reality you must stay within the manufacturer’s gap specification or you risk misfires and ignition issues.

Another misconception is that aftermarket universal-fit listings always fit perfectly; always confirm thread size, reach, and seat style before buying and be cautious of counterfeit listings by buying from reputable sellers.

Drivers Top Picks

When choosing between the SYKRSS 6240 Iridium, NGK Iridium IX, and NGK G‑Power for your 2004 Nissan Titan, you’ll mainly weigh long-term durability and ignition performance (the iridium options are favored for longer life and a more consistent spark) against upfront cost and proven fitment (the G‑Power is often picked when you want reliable performance on a budget). You’ll also consider ease of installation, pre-set gap and compatibility with your engine, and whether you value slightly better fuel economy and smoother idling over lower replacement expense.

Wrapping Up

You now have a clear shortlist of spark plugs that fit the 2004 Nissan Titan’s 5.6L V8 and why each one might suit your priorities. If you want the safest all-around pick, go with the NGK Iridium IX for proven performance and longevity.

If price matters most, the SYKRSS 8-pack delivers solid iridium performance at a lower cost. For a balance between performance and cost, the NGK G-Power and Autolite Platinum sets are good alternatives depending on availability.

Remember to replace all 8 plugs at once, verify the gap before installation (commonly ~0.044″), and use the correct socket and torque to avoid damage.
