MIKKUPPA UF549 Ignition Coil Pack & 9029 Iridium Spark Plugs Set of 4 — Copper‑Core Coils, 1‑Year Warranty

MIKKUPPA UF549 ignition coil pack paired with four 9029 iridium spark plugs is a direct-replacement ignition kit designed to restore reliable spark and steadier engine performance in compatible Nissan and Infiniti models.

This four-piece kit combines high-conductivity coil units (UF549) and long-life 9029 iridium spark plugs to replace worn ignition components in a range of Nissan and Infiniti vehicles. Each coil uses copper-core windings and heat-resistant epoxy housing for consistent spark delivery, while the iridium electrodes on the plugs help maintain efficient combustion over extended service intervals. The set ships with four coils and four plugs plus a 1-year warranty from MIKKUPPA.

Which vehicles does this MIKKUPPA ignition kit fit?

This kit targets specific Nissan and Infiniti petrol engines across many model years; compatibility spans compact cars, crossovers, pickup variants, and select Infiniti V8s. Always verify fit using your vehicle’s year, engine displacement, and the seller’s fitment checker before ordering.

• Nissan: Altima (2007–2018) 2.5L, Rogue (2008–2018) 2.5L, Sentra (2009–2019) variants, Versa, Cube, X-Trail, NV200, NP300/Frontier, March, Tiida, Pathfinder, Urvan.
• Infiniti: QX60 (2014–2017) 2.5L, Q70/Q70L/QX70 (2014–2019) and earlier FX/M/M56 V8 applications noted in fitment lists.
• Replaces OE references: UF549/UF-549, C1696, 5C1753, E1049, 22448JA00A for coils and 22401JA01B / 22401JA07B for plugs.

How do these coils and iridium plugs affect everyday driving?

Upgrading worn coils and plugs restores consistent ignition timing and combustion stability, reducing misfires and rough idle in many cases. Improved spark conductivity can help the engine run smoother during acceleration and at cruise speeds, especially on older ignition components.

• Faster, more reliable spark from copper-core coils for smoother idle and throttle response.
• Iridium plugs resist electrode wear, preserving ignition performance longer than standard plugs.
• Heat-resistant epoxy and reinforced housings reduce risk of coil deformation under engine heat.

What are the construction and durability features of the parts?

MIKKUPPA designs the UF549 coils with high-conductivity copper windings and strong dielectric epoxy to maintain electrical performance under thermal stress. The 9029 spark plugs use iridium center electrodes for a fine, durable point that preserves spark intensity and reduces gap wear.

• Copper core windings improve electrical flow and ignition consistency.
• Reinforced engineering plastic and epoxy resist heat and vibration damage.
• Iridium electrode provides a long service life and stable spark gap retention.

What comes in the package and what warranty is included?

The product is sold as a complete set of four ignition coils and four matching iridium spark plugs, ready to replace a full engine bank on 4-cylinder models or as required for specific Infiniti fits. MIKKUPPA backs the kit with a 1-year warranty and customer support for fitment or quality issues.

• Included: 4 x UF549 ignition coils and 4 x 9029 iridium spark plugs.
• Warranty: 1-year limited coverage from MIKKUPPA; prompt seller support for defects.
• Tip: Confirm OEM part numbers and use the fitment checker before purchase.

Who is this for: Technically minded DIYers, independent mechanics, or owners of compatible Nissan and Infiniti vehicles who need a budget-friendly, full-bank ignition refresh. If you want to replace worn coils and plugs at once—with parts built for heat tolerance and extended electrode life—this MIKKUPPA kit is a practical option. Always confirm vehicle compatibility and consult a technician for complex diagnostics or installation.
