Ignition Coil & Iridium Spark Plugs for Nissan NV2500 NV3500 (2012-2017) 5.6L V8

High-Output Ignition Coil & Iridium Spark Plugs for 2012-2017 Nissan NV2500, NV3500 (VK56DE / F80)

Restores ignition efficiency and eliminates misfires for heavy-duty hauling and fleet operations. This direct-replacement coil pack and iridium spark plug kit resolves incomplete combustion cycles, ensuring a strong, consistent spark for optimal fuel burn under load.

The Stock NV2500, NV3500 Ignition Weakness

The factory ignition coils on the VK56DE 5.6L V8 are notoriously prone to thermal degradation, especially given the heavy curb weight and sustained engine loads experienced by the F80 chassis. Over thousands of heat cycles, the epoxy potting compounds inside the OEM coils crack, allowing moisture intrusion and internal arcing. This leads to primary and secondary winding failure, resulting in a weak spark, persistent P0300-series misfire codes, rough idling, and drastically reduced fuel economy. Additionally, standard stock plugs wear down their electrodes rapidly under high-load commercial driving, widening the spark gap and overworking the failing coils until complete ignition failure occurs.

The Engineering Solution

This complete ignition overhaul utilizes high-grade copper wire windings and heavily insulated bobbins to significantly increase voltage output and resist thermal breakdown inside the cramped V8 engine bay. The ignition coils feature a reinforced dielectric boot and high-temperature silicone housings, completely sealing out moisture and preventing voltage leaks to the cylinder head. Paired with advanced iridium spark plugs, this kit delivers a highly focused, concentrated spark. Iridium's exceptionally high melting point ensures the electrode gap remains perfectly constant over an extended service life, optimizing the flame kernel for a complete, efficient fuel burn. This translates to restored torque curves, improved throttle response, and the elimination of hesitation when accelerating heavy payloads.
