Key Features

Premium Iridium Spark Plugs

The included iridium spark plugs provide excellent durability and consistent ignition performance.

Benefits include:

• Longer service life
• Stable spark under load
• Improved combustion efficiency
• Reduced maintenance intervals

Iridium electrodes resist wear significantly better than traditional copper spark plugs.

OEM-Style Spark Plug Wires

The ignition wire set is engineered to provide reliable voltage transfer while matching factory routing and installation points.

Advantages include:

• Direct replacement design
• Consistent spark delivery
• Reliable electrical insulation
• Easy installation

Proper spark transfer helps reduce misfires while supporting smoother engine operation.

High-Energy Ignition Performance

The ignition system components are designed to deliver:

• Strong spark output
• Reliable cold starts
• Smooth idle
• Better throttle response
• Stable engine performance

Restoring proper ignition energy can improve both drivability and fuel efficiency when replacing worn components.

High-Temperature Materials

The ignition wires utilize heat-resistant materials designed to withstand the demanding conditions inside the engine compartment.

This construction helps resist:

• High engine temperatures
• Oil exposure
• Moisture
• Age-related deterioration

Improved durability helps extend the service life of the ignition system.

Why Replace Spark Plugs and Wires Together?

Spark plugs and ignition wires work as a system.

Replacing both components during the same service helps:

• Restore balanced ignition performance
• Reduce engine misfires
• Improve fuel economy
• Improve throttle response
• Reduce future maintenance costs

This is especially beneficial for higher-mileage Nissan V6 engines.

Common Symptoms of Worn Ignition Components

If your ignition system is beginning to fail, you may notice:

• Rough idle
• Engine hesitation
• Poor acceleration
• Hard starting
• Check Engine Light
• Reduced fuel economy
• Cylinder misfires

A complete ignition tune-up often restores smooth engine operation and eliminates many common drivability complaints.

Installation Tips

For the best results:

1. Replace one ignition wire at a time.
2. Match each replacement wire with the original.
3. Install the new iridium spark plugs using factory torque specifications.
4. Fully seat each ignition wire.
5. Verify correct wire routing before starting the engine.

Completing the tune-up carefully helps ensure maximum ignition performance.
