Set of 6 Ignition Coil Packs & Spark Plugs Fits 3.5 V6 - Improved

In this review the reviewer tested the LCWRGS set of 6 ignition coil packs and spark plugs on V6 Nissan and Infiniti models to judge fit, reliability, and performance. The bottom line is that this kit is for owners who want a direct OEM-style replacement that can stop cylinder misfires and restore throttle response; the most compelling reason to buy is the claimed 15% energy upgrade over OE coils, which translates to firmer sparks and a practical return in drivability and reduced hesitation.

Key Features

• Broad vehicle compatibility: Works with many 3.5L V6 Nissan and Infiniti models so buyers can replace all six coils and plugs in a single service.
• OE replacement design: Direct OEM-style coils and plugs make installation straightforward and reduce the chance of clearance or connector issues.
• Improved ignition energy: New coils are designed to deliver about 15% more energy than the original units and can reduce misfires and hesitation.
• Durable construction: High dielectric epoxy and highly conductive copper wire improve connectivity and aim to extend service life under normal driving conditions.
• Complete kit: Includes a set of 6 coil packs and 6 spark plugs so all cylinders are serviced at once for balanced performance.

Who It's For

This kit is best for owners of compatible Nissan Maxima, Altima, Murano, Pathfinder, 350Z and select Infiniti models who are experiencing misfires, poor fuel economy, or a check engine light tied to ignition faults and want a straightforward repair. It suits DIY mechanics and independent shops that prefer replacing the entire bank of coils and plugs to restore even firing.

Drivers who need an exact factory part number match for a warranty claim or who require dealer-only branded components may want to look elsewhere, since this is an aftermarket replacement built to meet or exceed OE specifications rather than an original equipment brand part.

Pros & Cons

Cons

• Fitment opinions vary slightly among users, so a careful parts check before installation is advised.
