Ignition Coil & Iridium Spark Plugs for Nissan Titan (2008-2015) 5.6L V8

High-Output Ignition Coil & Iridium Spark Plugs for 2008-2015 Nissan Titan (VK56DE/A60)

Restores Factory Firing Voltage: This comprehensive ignition overhaul kit replaces degraded OEM coils and fouled plugs to restore optimal firing voltage, eliminate misfires, and improve combustion efficiency in the 5.6L VK56DE powertrain.

The Stock A60 Titan Thermal Degradation

The OEM ignition coils on the A60 Titan are notoriously prone to thermal degradation over extended mileage. The VK56DE V8 engine produces significant under-hood temperatures, which gradually break down the epoxy potting inside the factory coils, leading to internal shorting and weakened spark output. Coupled with standard spark plug electrode wear, this results in incomplete combustion, hesitation under heavy load or towing conditions, rough idling, and persistent P0300-series misfire codes. Eventually, this degraded spark efficiency reduces fuel economy and diminishes the critical low-end torque output required for heavy hauling.

The Engineering Solution

This direct-replacement ignition package upgrades the system with precision-wound primary and secondary copper windings to deliver a higher energy spark with faster recovery times between firing events. The upgraded coil housings utilize high-dielectric epoxy and advanced thermal-resistant polymers to withstand continuous extreme engine bay heat without degrading. Paired with the included Iridium spark plugs—featuring an ultra-fine center electrode that requires less voltage to bridge the gap—the system ensures a highly concentrated and stable spark. This engineered combination stabilizes the idle, supports optimal fuel burn, and fully restores the lost horsepower and torque necessary for heavy towing or continuous payload hauling.
