Ignition Coil & Iridium Spark Plugs for Nissan Quest (2011-2017) 3.5L

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2011-2017 Nissan Quest (VQ35DE / E52)

Restores lost ignition efficiency and eliminates misfires: This complete ignition coil and iridium spark plug kit replaces degrading factory ignition components to restore optimal combustion, stabilize idle, and resolve misfire-related diagnostic trouble codes (DTCs) like P0300 through P0306.

The Stock Quest Ignition Degradation

The transverse-mounted VQ35DE in the E52 Nissan Quest creates a highly restrictive thermal environment, particularly for the rear bank of cylinders against the firewall. Over thousands of heat cycles, the factory ignition coil epoxy potting degrades, leading to micro-cracking in the housing. This thermal breakdown causes voltage leakage, which reduces the spark energy delivered to the cylinder. Simultaneously, the OEM platinum or standard iridium spark plugs experience electrode erosion. As the spark gap widens, the coils are forced to work harder to arc, creating a compounding failure loop that manifests as rough idling, hesitation under acceleration, and decreased fuel economy.

The Engineering Solution

This comprehensive ignition overhaul kit is engineered to withstand the extreme underhood temperatures of the VQ35DE platform. The updated ignition coils feature high-temperature dielectric epoxy and upgraded primary and secondary copper windings that ensure maximum voltage transfer without thermal breakdown. The included iridium spark plugs utilize an ultra-fine wire iridium center electrode and a tapered ground electrode to minimize quenching and provide a consistently dense spark. This material combination requires less firing voltage from the coils, directly extending coil lifespan while ensuring a complete fuel burn. By replacing the coils and plugs simultaneously, you re-establish baseline ignition timing, restoring factory throttle response, preventing unburnt fuel from damaging the catalytic converters, and ensuring reliable daily performance.
