Ignition Coil and Iridium Spark Plugs for Nissan Titan (2016-2020) 5.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2016-2020 Nissan Titan (A61)

What it Does: The ignition coil and iridium spark plug kit refreshes the complete secondary ignition circuit on the 2016-2020 Titan to eliminate misfires and restore combustion efficiency under load.

The Stock Nissan Titan Ignition Degradation

In the direct-injected VK56VD V8, combustion chamber pressures and cylinder head thermal loads accelerate ignition component wear. Over time, the internal primary and secondary windings within the factory coil-on-plug (COP) modules experience dielectric breakdown due to sustained heat soak. Concurrently, factory spark plug gaps erode, elevating secondary resistance and placing higher electrical strain on aging coils. This causes unburned fuel, sluggish throttle response, reduced fuel economy, and diagnostic fault codes P0300 through P0308.

The Engineering Solution

This comprehensive tune-up kit replaces the entire ignition array with high-density epoxy-potted coils and fine-wire iridium spark plugs. The coils feature reinforced thermal-resistant boots and precise 3-pin blade connectors to eliminate arching and resist breakdown from extreme underhood temperatures. The matching spark plugs feature a 0.039–0.043 inch pre-set gap and fine-wire iridium center electrodes, significantly reducing the ignition voltage required to jump the spark gap. This delivers a stable, hot spark kernel tailored to direct-injected air-fuel charges.

Frequently Asked Questions & Fitment Warnings

Does this fit the A61 Titan?

Yes, this is a direct fit for the 2016-2020 Nissan Titan equipped with the VK56VD engine. This kit does not fit 2004-2015 first-generation Titan models equipped with the port-injected VK56DE engine.

Do I need to adjust the spark plug gap before installation?

No, the iridium spark plugs come pre-set to 0.039–0.043 inches; handle the tips carefully during installation to avoid damaging the fine-wire center electrode.

The Nissan Titan Standard

Engineered to handle sustained heavy towing loads, severe vibration, and extreme duty cycles, this ignition package ensures consistent cylinder pressure without voltage drop or misfires when pulling heavy payloads.
