Ignition Coil Packs & Spark Plugs Compatible with V6 3.5L 2009-2020

In this review of the Ignition Coil Packs & Spark Plugs Compatible with V6 3.5L 2009-2020, the bottom line is that this pack is a practical, affordable repair option for owners of compatible Nissan and Infiniti V6 models who need to address misfires or rough idle. The reviewer found the combined set of six coils and six pre-gapped spark plugs to be a straightforward swap that restores engine smoothness and can clear a check engine light when failures are coil- or plug-related. It is best for DIY mechanics and budget-conscious owners who value fit and easy installation more than extended warranty backing.

Key Features

• Complete pack: Includes 6 ignition coils and 6 pre-gapped spark plugs so all cylinders are serviced at once, reducing diagnosis time and part mismatch risk.
• Wide vehicle fit: Designed to fit many V6 3.5L and related models from 2007 to 2020, which simplifies parts selection for owners of Maxima, Murano, Altima, Pathfinder and several Infiniti models.
• OEM numbers referenced: Matches part numbers such as UF550, 22448JA10A and 22448ZE00A so installers can cross-check compatibility with factory references.
• Performance restoration: Intended to resolve common symptoms like engine misfire, hard starts, rough idle and decreased power when original coils or plugs fail.
• Pre-gapped plugs: Spark plugs arrive pre-gapped to the expected clearance to save setup time during installation.

Who It's For

This kit is ideal for DIY mechanics and independent shops servicing Nissan and Infiniti V6 engines that match the listed years and part numbers. It works well for owners who want a single-sku solution to replace all coils and plugs together to eliminate intermittent misfires and improve fuel economy.

It is less appropriate for drivers who need OEM dealer warranty coverage or who prioritize long-term proven longevity over upfront value; some customers reported mixed results on lifespan, so those seeking an extended-life OEM-only part may want to compare options.

Pros & Cons

Cons

• Longevity varies: some customers experienced early failures after a few months, so long-term durability appears mixed.
• No dealer warranty coverage implied: buyers wanting manufacturer-backed long warranties may prefer OEM replacements.
