A-NAFTULY Iridium Spark Plugs 4-Pack LFR5AIX-11 (4469) for 2.5L 4-Cyl — 0.6mm Fine-Wire, Long-Life

A-NAFTULY Iridium Spark Plugs (4-pack, LFR5AIX-11 / 4469) are high-durability replacement plugs engineered to restore consistent ignition and improve fuel efficiency for many 4-cylinder vehicles.

These four iridium-tipped spark plugs are designed as direct-fit replacements for a long list of makes and models — including Toyota Camry, RAV4, Highlander, Venza, Scion tC, Nissan Altima and Sentra, plus select Hyundai, Kia, Jeep and Chrysler applications. Built with a 0.6mm fine-wire iridium center electrode and laser-welded construction, they prioritize reliable spark, extended life, and reduced fuel waste compared with older worn or OEM-standard plugs.

Which vehicles will these LFR5AIX-11 spark plugs fit?

These plugs match many 4-cylinder engines across Toyota, Nissan, Hyundai, Kia, Jeep, Chrysler, Dodge and Ram lineups. They’re sold as part number 4469 and cross-reference many OEM and aftermarket codes, making them a broad-fit replacement when the LFR5AIX-11 specification is required.

• Toyota: Camry, RAV4, Highlander, Venza, Sienna, 2010–2017 ranges where 2.5L/2.7L L4 engines apply

How do these spark plugs help performance and economy?

The 0.6mm iridium fine-wire center tip concentrates the spark for cleaner combustion and better ignition reliability. Iridium’s high melting point and hardness reduce electrode wear, which can keep timing and fuel burn more consistent over longer service intervals.

• Fine-wire tip lowers required voltage for ignition, aiding cold starts
• Laser-welded construction improves electrode longevity and stability
• Durable iridium alloy reduces fouling and extends service life

What are the build quality and materials like?

These plugs use an iridium center electrode that’s significantly harder than platinum and resists heat and electrical erosion. The plug assembly is manufactured with precision to match OEM heat range and thread specifications, helping ensure correct fit and long-term durability.

• Iridium center electrode for high-temperature durability
• Precision thread and seat dimensions for proper sealing and torque
• Manufactured to cross-reference numbers such as XP5325, LFR5AGP and others

How easy is installation and what’s included?

Installation is straightforward for anyone comfortable with basic engine maintenance: remove the old plugs, verify gap and torque to the specified value, then install the new set. A-NAFTULY ships a set of four plugs and backs them with a 12-month limited warranty and customer support for fitment questions or concerns.

• Package contains four LFR5AIX-11 (4469) iridium spark plugs
• Recommended: check manufacturer gap and torque specs before install
• 12-month worry-free warranty and A-NAFTULY customer support included

Who is this for: Drivers and independent technicians who need a reliable, long-lasting replacement for worn spark plugs on common 4-cylinder vehicles. These A-NAFTULY iridium plugs are suited for owners seeking improved ignition consistency and extended service life compared with older standard plugs, without changing engine components or tuning.
