ENA Iridium Spark Plug and Ignition Coil Set 6-Pack - Reliable Fit

Our review finds this ENA set of six iridium spark plugs and six ignition coil packs to be a practical replacement option for owners of many Nissan and Infiniti 3.5L V6 models. The bottom line: it is for drivers who need an affordable, OE-style swap that installs quickly and restores reliable ignition performance. In this review the standout reason to buy is straightforward compatibility across many model years and a design intended for original equipment and replacement applications, which simplifies part selection for routine tuneups.

Key Features

• Engineered for OE fit: The components are designed to match original equipment fit and function so they install without modification and sit correctly in the engine bay.
• Iridium spark plugs: The iridium tips aim to provide consistent spark and improved starting performance compared with older worn plugs.
• Durable coil construction: The coils are manufactured to operate under varied conditions so they maintain ignition performance across normal driving cycles.
• Wide vehicle coverage: This set lists compatibility for many Nissan and Infiniti 3.5L models, reducing the risk of a wrong-parts purchase for common V6 cars and SUVs.
• Quick installation: Customers report the parts install easily, making this a sensible option for DIY mechanics or shops performing routine replacement.

Who It's For

This set is best for owners of Nissan Altima, Maxima, Murano, Pathfinder, 350Z and Infiniti models with the 3.5L V6 who need a full replacement of both spark plugs and ignition coils. It suits DIYers comfortable removing coils and plugs and independent installers who want a consolidated kit to service all six cylinders.

Shoppers who require factory-branded parts for dealer service or those who need extended long-term durability guarantees should consider OEM units or higher-end aftermarket options instead, since some users report concerns about long-term coil durability and mixed feedback on spark plug longevity.

Pros & Cons
