BULIAZY 4pc Ignition Coil Pack & Spark Plugs Kit for Nissan and Infiniti

Upgrade your Nissan and Infiniti ignition system

Upgrade your ignition system with the BULIAZY 4pc Ignition Coil Pack and Spark Plugs Kit. This comprehensive set is designed to fit a wide range of Nissan and Infiniti models, delivering a balanced mix of reliability and performance without the guesswork of compatibility.

Quality that stands up to daily driving. Each coil pack uses Japan-imported rubber seals and a Germany-imported varnished wire to endure heat, vibration, and long drives. The iridium spark plugs are paired with coil packs to deliver consistent ignition energy, helping the engine burn fuel more evenly across cylinders. The kit claims up to 15% more energy than OE coils, offering potential for improved throttle response and smoother idle—though results can vary by vehicle and driving conditions.

What’s included and how it helps. This set features four ignition coil packs and four iridium spark plugs. Its interchange parts list includes UF549, C1696, 5C1753, E1049, and more, allowing direct replacement for many OEM units. Engineered for a straightforward swap, it minimizes downtime and helps customers complete upgrades in a single session.

Real‑world use cases. If your vehicle experiences hard starts, misfires, or decreased power, a coil and plug refresh can bring back confident starts and cleaner engine operation. Users may notice steadier idle and more consistent ignition energy during acceleration, especially under load. Always follow vehicle service guidance and consult the fitment chart to ensure correct compatibility.
