Ignition Coil & Iridium Spark Plugs for Nissan Maxima (2009-2023) 3.5L

Direct-Fit Ignition Coils & Iridium Spark Plugs for 2009-2023 Nissan Maxima (VQ35DE / A35, A36)

Restores spark intensity and combustion efficiency: Replaces degraded factory coils and worn plugs to cure misfires, rough idle, and poor fuel economy under heavy engine load.

The Stock Maxima Ignition Breakdown

The OEM VQ35DE ignition system is prone to thermal degradation due to excessive heat soak in the transverse V6 engine bay, particularly affecting the rear bank (firewall side) coils. Over time, the factory ignition coil epoxy cracks and internal copper windings degrade, increasing electrical resistance and dropping voltage output. Coupled with standard spark plugs experiencing rapid electrode erosion, this combination leads to a weak spark kernel, pre-ignition events, sluggish throttle response, and the inevitable P0300 to P0306 misfire diagnostic trouble codes.

The Engineering Solution

This ignition coil and iridium spark plug kit is engineered to exceed factory A35 and A36 specifications. The updated coils feature advanced high-temperature epoxy and highly conductive internal copper windings, minimizing voltage loss and preventing premature breakdown caused by relentless engine bay thermal cycling. Paired with precision laser-welded iridium center electrode spark plugs, this combination guarantees a concentrated, high-voltage spark kernel capable of piercing peak cylinder pressures. The ultra-fine iridium tip requires less firing voltage while providing superior resistance to high-heat gap erosion, ensuring stable combustion, restored low-end torque, and perfectly consistent ignition timing throughout the entire RPM band.
