Autowxjq 6-Piece Iridium Spark Plug & Coil Pack UF550 for Nissan/Infiniti

Overview

The Autowxjq 6-piece Iridium Spark Plug and Ignition Coil Pack is designed to help Nissan and Infiniti V6 engines maintain consistent ignition performance. Each spark plug is iridium-based and pre-gapped for direct installation, while the matching ignition coils are engineered to deliver reliable energy to every cylinder. This kit targets original equipment replacement needs and is compatible with a wide array of 3.5L and 3.7L V6 models from Nissan and Infiniti, making it a practical choice for many daily drivers and weekend rides alike.

When you replace spark plugs and ignition coils in a synchronized manner, you may experience more stable starts and smoother engine feel across RPMs. The parts are built to endure varied driving conditions, from city commutes to highway stretches, with a focus on consistent electrical delivery and durable construction. The result is a setup that you can install with confidence and drive on with less worry about intermittent misfires or weak starting performance.

What’s Included and Why It Matters

• Six pre-gapped iridium spark plugs ready for direct installation, reducing setup time and guesswork
• Six ignition coils matched to the plugs for balanced energy delivery across the engine
• Designed as UF550 replacement capability to fit a broad Nissan/Infiniti lineup
• Rugged construction intended to withstand a range of driving conditions and climates

Possible Daily-Use Benefits

• Potential for crisper ignition, which can help smooth idle and responsive acceleration
• Consistent spark and coil performance may contribute to steadier power delivery on demand
• Replacing both parts together can reduce the likelihood of ignition-system-side dysfunctions over time
• Suitable for a wide range of models, including popular Nissan/Infiniti 3.5L and 3.7L V6 engines

Compatibility spans a broad set of vehicles from around 2007 to 2020, including Altima, Maxima, Murano, Pathfinder, Quest, 370Z, and other Infiniti models with V6 power. In practice, owners report a noticeable difference in starting reliability and a more consistent feel when cruising or accelerating after installation. The kit’s design emphasizes ease of use and a direct path to restoring ignition performance without extra adaptations or specialized tools. As with any maintenance, following proper torque specs, gap checks, and installation steps will help you achieve the best possible outcome.
