Ignition Coil & Iridium Spark Plugs for Nissan Armada (2007-2015) 5.6L V8

Direct-Replacement Ignition Coils & Iridium Spark Plugs for 2007-2015 Nissan Armada (VK56DE / WA60)

This comprehensive ignition service kit replaces degraded factory coils and fouled plugs to restore optimal combustion, eliminate misfires, and stabilize idle in the 5.6L V8.

The Stock VK56DE Ignition Degradation

Over time and mileage, the factory ignition coils on the VK56DE engine are highly susceptible to thermal breakdown due to the inherent heat soak of the engine bay. The dielectric epoxy within the OEM coils cracks from repeated thermal cycling, leading to internal voltage leaks, under-load misfires, and a noticeable drop in fuel economy. Concurrently, standard or worn spark plugs suffer from widened gap tolerances. This strains the secondary ignition system, reduces combustion efficiency, and ultimately results in sluggish throttle response and rough idling characteristics.

The Engineering Solution

This package utilizes advanced Iridium spark plugs and high-dielectric ignition coils to optimize the burn cycle. The iridium center electrode offers an exceptionally high melting point, ensuring precise spark focus and resisting gap erosion over an extended service life. The direct-replacement 3-blade coils feature upgraded thermal-resistant epoxy and dense copper primary and secondary windings, which mitigate the effects of extreme engine bay temperatures. By delivering a more intense and consistent spark, this system ensures a complete fuel burn, effectively restoring factory horsepower and torque curves while preventing the dreaded P0300 series misfire codes.
