MIKKUPPA Ignition Coil and Spark Plug Kit UF549 + 9029 — Set of 4 Coils & 4 Plugs for Nissan/Infiniti 2007–2019, Copper-Core Durab

This replacement kit is designed for owners and mechanics who need a complete ignition refresh without hunting for matched parts. The set includes four UF549-style ignition coils and four 9029 spark plugs engineered to match OE fitment and electrical characteristics for a wide range of 1.6L–5.6L engines. Built with high-conductivity copper cores and reinforced epoxy housings, these components aim to deliver reliable spark delivery and durable heat resistance under typical driving conditions.

Which vehicles and engines are covered by this MIKKUPPA kit?

This kit replaces the OEM coil part numbers like UF549 and other referenced numbers, and it fits many Nissan compact cars, sedans, crossovers, and select Infiniti models. Compatibility covers multiple years and displacements; always verify fit using your vehicle details before ordering.

• Nissan: Altima, Sentra, Rogue, Versa, Cube, NV200 across 1.6L, 1.8L, 2.0L, 2.5L engines (2007–2019 ranges vary by model).
• Infiniti: QX60, Q70, Q70L, QX70, FX50, M56 with 5.0L/5.6L V8 or relevant L4 models where listed.
• Replace part numbers: UF549, UF-549, C1696, 5C1753, E1049, 22448JA00A and spark plug references 9029, 22401JA01B, 22401JA07B.

How will these coils and plugs affect everyday driving?

When installed as a matched set, new coils and plugs restore consistent spark timing and combustion initiation, which helps the engine run more smoothly and reduces misfires. While exact fuel economy gains depend on the vehicle’s condition, fresh ignition components typically support steadier idle and throttle response.

• Promotes steadier idle and fewer misfires under normal driving.
• Supports more consistent throttle response after installation.
• Designed for heat resistance to maintain performance in typical engine conditions.

What are the build and material highlights of the MIKKUPPA parts?

MIKKUPPA coils use high-conductivity copper cores and a high-dielectric epoxy to support reliable electrical conduction and resist breakdown. The outer housings combine epoxy resin and reinforced engineering plastics to resist heat-induced deformation and preserve insulation.

• Copper coil cores for stable electrical transfer.
• High-dielectric epoxy and reinforced plastic housings for thermal durability.
• Heat-pressure tested for stable output under elevated temperatures.

What should you check before you buy and how is support handled?

Confirm your vehicle year, engine size, and OEM part numbers before purchasing to ensure compatibility; use the vehicle-fit tool on the product page. MIKKUPPA supplies the set with a 1-year warranty and customer support to address fitment issues or defects.

• Check “amazonconfirmfit” or your OEM part number (see OE references) before ordering.
• Package contents: 4 ignition coils + 4 spark plugs.
• MIKKUPPA offers a 1-year warranty and direct customer support for issues.

Who is this for: This MIKKUPPA ignition coil and spark plug set is ideal for DIY mechanics, independent repair shops, and owners of compatible Nissan or Infiniti models who need a full-bank replacement. It’s most appropriate when one or more coils or plugs show symptoms like rough idle, misfire codes, or intermittent performance issues and you prefer a matched set to restore balanced ignition across cylinders.
