MIKKUPPA Ignition Coil Pack & Iridium Spark Plug Kit, Set of 4 UF549/9029 — Direct-Fit for Nissan/Infiniti

MIKKUPPA UF549 ignition coil pack and 9029 iridium spark plug set of four replaces worn coils and plugs to restore reliable spark and smoother engine response for compatible Nissan and Infiniti models.

This matched kit combines four ignition coils and four iridium spark plugs designed as direct-fit replacements for a long list of Nissan and Infiniti engines. Built with high-conductivity copper cores and reinforced housings, the components are engineered to resist heat and maintain steady electrical output, helping the ignition system fire consistently under normal driving and demanding conditions.

Which vehicles will this MIKKUPPA set fit?

The kit covers many Nissan and Infiniti models across several years and engine sizes. Always cross-check part numbers and your vehicle’s compatibility before ordering to ensure a correct fit.

• Nissan models: Altima, NV200, Versa, Sentra, Rogue, Cube, X-Trail, NP300/Frontier, March, Urvan, Tiida, Pathfinder (various years and engines listed).
• Infiniti models: QX60, FX50, M56, Q70/Q70L, QX70 (selected years and V8/L4 engines).
• Replace OE numbers: UF549 (coils) and 9029/22401JA* (spark plugs); check "amazonconfirmfit" for exact fitment.

How do these coils and plugs improve performance?

The coils use copper cores and a high-dielectric epoxy to deliver strong, consistent current to the spark plugs, while the iridium tips on the plugs require less voltage and resist erosion. Together they promote a cleaner, more complete burn when the engine is within its designed operating range.

• Faster, more consistent ignition pulses thanks to high-conductivity copper cores.
• Durable epoxy and reinforced plastic housings withstand engine bay heat and pressure.
• Iridium spark plugs offer longer service intervals and stable electrode gaps.

What should I expect during installation and maintenance?

These are designed for direct replacement of the OE coils and plugs, so installation follows the original coil locations and plug torque specs. Basic hand tools and standard ignition-coil removal procedures are typically sufficient; if you’re unsure, a mechanic can swap the set quickly.

• Replace coils and plugs in matched sets to maintain balanced firing across cylinders.
• Follow vehicle torque specs and gap recommendations when installing spark plugs.
• Inspect wiring boots and connectors for corrosion or damage during service.
