Ignition Coil and Iridium Spark Plugs for Nissan Titan (2004-2007) 5.6L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2004-2007 Nissan Titan

What it Does: Restores factory secondary ignition voltage and combustion efficiency by replacing worn coil packs and fouled plugs across all eight cylinders to eliminate under-load misfires.

The Stock Titan Ignition Breakdown

On the VK56DE platform, factory coil-on-plug assemblies endure extreme thermal cycling inside deep cylinder head wells. Over time, heat soak degrades the internal insulation and potting epoxy, causing internal dielectric breakdown, secondary voltage arcing, and carbon tracking. This results in rough idling, hesitation during acceleration, reduced towing performance, and intermittent P0300–P0308 trouble codes.

The Engineering Solution

This 8-cylinder ignition overhaul kit pairs high-output coil-on-plug assemblies with fine-wire iridium spark plugs. Each coil features premium electrolytic copper windings, direct-fit OEM blade connectors, and heat-resistant silicone boots to insulate against high under-hood temperatures. The fine-wire iridium center electrodes reduce required firing voltages, ensure stable spark kernel generation, and prevent electrode erosion under sustained high-load conditions.
