AULINK Ignition Coil Pack UF549 4pcs for Nissan Altima Rogue Sentra 2.5L L4 — OE-Style, Heat-Resistant Replacement

If your vehicle shows intermittent misfires, rough idle, or reduced fuel efficiency, worn ignition coils are a common cause. These AULINK UF549 coils are made as OE-style replacements and are offered as a 4-piece set to service four cylinders at once. They are engineered for heat and impact resistance, come from TS16949-certified production, and undergo full function and leakage testing to help match factory performance.

Which cars and engines will these coils fit?

These ignition coils are designed to replace the factory coils on a range of Nissan and Infiniti models with inline-four and some V8 engines. Fitment covers multiple model years and displacements — check the vehicle list and part numbers against your VIN to confirm compatibility.

• Primary fit: Nissan Altima 2007–2018 with 2.5L L4, and Altima 2019 with related L4 engines.
• Also fits Nissan Rogue, Rogue Select, Sentra, Versa, March, NP300 across specified years and displacements in the product details.
• Includes compatibility for select Infiniti models such as Q70, Q70L, QX70, QX60 and older FX50/M56 V8s noted in the fitment list.
• Cross-references multiple OEM numbers (UF549, UF-549 and listed alternates) for quick verification.

How do these coils improve engine performance?

By providing a strong, consistent spark and resisting heat and corrosion, new coils help the ignition system operate reliably under load. Replacing failing coils reduces misfires and can restore smoother throttle response and combustion stability without changing other engine components.

• High-temperature construction minimizes heat-related degradation during extended driving.
• Trivalent metal-plated contacts resist corrosion to maintain good electrical connection.
• Designed to lower ICM (ignition control module) stress by providing stable primary and secondary output.
• 100% function and leakage tested to reduce the chance of early failure after installation.

What should I expect during installation and maintenance?

Installation follows standard ignition coil replacement steps: disconnect battery, remove engine covers if needed, unplug connectors, and unbolt the coils from the valve cover. No special tuning is required after swap; simply clear any stored codes if present and perform a short test drive to confirm correct operation.

• Sold as a 4-piece set to replace four coils at once for consistent wear level.
• Use basic hand tools; follow vehicle service manual torque specs for bolt tightening.
• Inspect spark plug condition while coils are out — replace plugs if worn for best results.
• Recommended follow-up: scan for codes and verify no misfire codes remain after installation.

Who is this for: The AULINK UF549 4-piece ignition coil set is aimed at DIY mechanics, independent shops, and fleet owners who need an affordable OE-equivalent replacement for Nissan and select Infiniti vehicles listed in the fitment. If you want durable coils that resist heat and corrosion and come with factory-level testing and a one-year/50,000 km support window, this kit is built for that purpose. Always confirm part numbers and engine codes before purchasing to ensure a correct match for your vehicle.
