Product overview

The ECCPP UF550 kit is a complete replacement solution designed for a broad range of Infiniti and Nissan 3.5L V6 engines. It brings together six ignition coils and six iridium spark plugs, coordinated to deliver a consistent ignition sequence and a smoother overall driving experience. The components are engineered to work as a system, so you can expect cleaner starts, steadier idle, and responsive performance across trips and daily commutes.

What’s included

  • Six ignition coils
  • Six iridium spark plugs (model 1406)
  • Robust wiring and corrosion-resistant connectors designed for reliable connections

Quality and design

Constructed to meet or exceed OE specifications, the UF550 parts use high-conductivity copper wiring and a durable epoxy seal to resist vibration and maintain electrical integrity. The design aims to deliver improved energy delivery compared with older components, which may translate to more confident cold starts and steadier engine response across operating conditions.

Why consider this kit

  • May produce smoother engine running and more consistent ignition across compatible models
  • Designed as a cohesive coil-and-plug replacement to reduce mismatched performance
  • Potential for improved cold-start behavior and steady acceleration in everyday driving
