Ignition Coil Packs for 2002-2009 Nissan V6 - Set of 6

In this review of the Ignition Coil Packs set of 6, the bottom line is simple: these coils are aimed at owners of 3.5L or 4.0L V6 Nissan, Infiniti and compatible Suzuki models who need a direct-fit replacement that restores smooth running and fixes misfires. The reviewer found the coils to be straightforward to install, drop-in replacements for the listed OEM numbers, and engineered for improved conductivity and durability. For anyone troubleshooting rough idle, hesitation, or an engine error light on the specified vehicles, this set offers an affordable way to bring the engine back to normal operation.

Key Features

• Direct OEM fit: Designed to replace OEM part numbers UF349, C1406 and others, so installation is typically plug-and-play without modifications.
• Premium construction: Built with highly conductive copper wire and high dielectric epoxy to improve connectivity and resist breakdown under heat and vibration.
• Compatibility: Covers 3.5L and 4.0L V6 Nissan and Infiniti models from the listed years plus compatible Suzuki Equator and Xterra applications, reducing the need to search for multiple SKU types.
• Performance upgrade: Manufacturer claims up to 15% more power than aging OE coils, which can translate to fewer misfires and smoother acceleration in worn engines.
• Complete kit: Supplied as a full set of 6 coils so all cylinders use matched units, helping restore balanced firing and fuel efficiency.
• Support and warranty: Ships with a 24-month warranty and seller support to resolve installation or performance questions.

Who It's For

This set is best for owners and DIY mechanics who drive 3.5L or 4.0L V6 Nissan, Infiniti or compatible Suzuki vehicles from the 2002 through 2013 model years listed, and who are experiencing misfires, reduced fuel economy, hesitation, or a check engine light tied to ignition faults. Because the pack replaces all six coils, it is a sensible choice when multiple cylinders show issues or when a matched set is preferred to avoid uneven performance.

It is not aimed at drivers who need a single coil for a different engine family, or those seeking OEM dealer-only branded parts for warranty reasons. Professional shops that require factory branded coils for manufacturer warranty work may want to source OEM units instead.

Pros & Cons

Pros

• Easy direct fit for the listed Nissan, Infiniti and Suzuki V6 engines, making DIY replacement quick and predictable.
• Improved conductivity and dielectric materials promise longer life and more consistent spark delivery than worn originals.
• Sold as a matched set of 6, which helps eliminate cylinder imbalance and ensures uniform performance.

Cons

• Some customers report mixed impressions of long-term durability, so results can vary by driving conditions and installation care.
• Not an OEM-branded coil, so buyers seeking factory-labeled parts for warranty reasons should check with their dealer.
