BELKEBIR Ignition Coil Pack & Iridium Spark Plug Kit, 4‑Pack Direct-Fit for 2007–2019 Nissan & Infiniti, OEM Replacement

BELKEBIR's set of four ignition coil packs and iridium spark plugs is a direct-fit replacement kit engineered to restore reliable spark and consistent engine performance for many 1.6L–5.6L Nissan and Infiniti engines from 2007–2019.

This complete ignition kit combines four UF549-style coil packs with high-quality iridium spark plugs to match factory specifications and deliver a straightforward plug-and-play swap. Designed for a broad range of Nissan and Infiniti models — from compact Sentra and Versa engines to larger Frontier and Infiniti V8s (applicable cylinders noted) — the kit addresses common ignition wear points so your engine runs smoother, starts reliably, and maintains fuel efficiency.

Which vehicles and engines will this ignition kit fit?

The BELKEBIR kit fits many Nissan models with 1.6L, 1.8L, 2.0L and 2.5L L4 engines and selected Infiniti models with 2.5L L4 or 5.0L/5.6L V8 engines (some Infiniti V8 fits only cylinders 1–6). Always cross-check with your vehicle VIN and engine code before purchase to ensure correct fitment.

• Common Nissan fits: Altima, Rogue, Sentra, Versa, Cube, Frontier, NV200, Pathfinder, Murano (various years 2007–2019 as listed).
• Infiniti fits: QX60, Q70, Q70L, FX50, M56, QX70 (model years and cylinder restrictions apply).
• Replaces OEM numbers including UF549, 22448-JN10A and spark plug part numbers like 9029 and 22401-series.

How do these components improve my car’s ignition behavior?

The coils deliver consistent high-energy output while the iridium plugs offer fine electrode wear resistance, working together to produce stable ignition events. That combination can reduce misfires, smooth out idle and support better throttle response without altering engine design.

• High-energy coil design for steady spark under load.
• Iridium electrodes resist wear longer than standard plugs.
• Engineered to meet or exceed OEM electrical and physical specs.

Is installation difficult and what should I expect during replacement?

Installation is intended to be straightforward: the ignition coils are direct OEM-style replacements and the spark plugs use factory thread size and reach. Basic hand tools and standard automotive procedures are sufficient for a competent DIYer; replace coils and plugs with the engine cold and follow proper torque specs for plugs.

• Plug-and-play coil connectors and mounting points match OEM locations.
• Torque the spark plugs to manufacturer spec and gap per instructions if provided.
• Inspect wiring boots and coil harnesses; replace any damaged clips during service.

What performance and maintenance benefits will I notice after swapping to this kit?

After replacing worn ignition parts, expect more consistent starts and fewer misfire-related faults. Improved combustion stability supports smoother acceleration and can help maintain optimal fuel usage; iridium plugs extend service intervals compared with conventional plugs.

• Cleaner, more reliable starts in varied conditions.
• Reduced engine hesitation and fewer misfire codes.
• Longer spark-plug life from durable iridium electrodes.

Who is this for: This BELKEBIR ignition coil and iridium spark plug set is aimed at owners and mechanics of Nissan and Infiniti vehicles within the listed model years who want a direct OEM-style replacement to restore dependable ignition performance. It's suitable for DIY enthusiasts comfortable with routine engine maintenance and professional shops performing engine tune-ups or troubleshooting misfires.
