Description
xPremium replacement for Nissan and Infiniti engines
Meet the Marsram UF549 ignition coil pack paired with spark plug 9029—a ready-to-install replacement set designed to support consistent ignition performance across a broad range of Nissan and Infiniti models. This 4-pack blends robust ignition coils with precision iridium plugs, offering a practical option for drivers seeking dependable starts and efficient combustion without committing to a full service overhaul.
Construction and materials are chosen with real-world driving in mind. The coil exterior uses epoxy resin and high-strength engineering plastic to stand up to engine heat and vibration, while the interior copper coil delivers high conductivity for a quicker, more reliable spark event. The spark plugs feature double iridium electrodes and a refined center design to promote stable ignition over time. Corrosion-resistant center and ground electrodes help preserve spark gap integrity, contributing to steady performance as miles accumulate.
Why this combo makes sense
- Heat-resistant exterior materials protect critical components under demanding driving conditions.
- High-conductivity copper coils can contribute to faster ignition response and improved throttle feel.
- Iridium-enhanced spark plugs support robust, consistent combustion and longer service life.
- Durable electrodes minimize wear and help maintain spark efficiency over time.
- Wide compatibility simplifies maintenance planning across multiple Nissan and Infiniti models.
What you get and how to install
- Set includes four UF549 ignition coils and four 9029 spark plugs, ready for replacement on compatible engines.
- Suitable for inline-4 and V8 configurations with engines from about 1.6L to 5.6L; verify fitment for your year/model.
- Basic replacement process: disconnect the battery, label wiring, and follow vehicle-specific torque specs from your service manual.
- Inspect surrounding ignition components and wiring during replacement to support a clean installation.
