Ignition Coil & Iridium Spark Plugs for Nissan Quest (2004-2009) 3.5L V6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2004-2009 Nissan Quest

Restores proper spark delivery: This complete ignition service kit replaces worn factory coils and fouled plugs to eliminate misfires, rough idling, and poor fuel economy in the 3.5L VQ35DE engine.

The Stock VQ35DE Ignition Failure Points

Over time, the factory ignition coils on the 2004-2009 Nissan Quest are prone to thermal degradation due to their placement within the tightly packaged VQ35DE engine bay. Constant heat cycling breaks down the epoxy resin and internal windings, leading to increased resistance, weak spark output, and eventual coil casing failure. This manifests as P0300 to P0306 misfire codes, engine hesitation under load, and unburned fuel that can prematurely destroy the catalytic converters. Additionally, standard factory plugs experience rapid electrode wear, widening the plug gap and further straining the aging ignition coils to bridge the arc.

The Engineering Solution

This comprehensive ignition kit utilizes upgraded dielectric epoxy and high-temperature silicone boots to withstand the harsh thermal environment of the V42 chassis. The redesigned primary and secondary copper windings ensure a highly conductive, low-resistance path, producing a hotter, more consistent voltage output. Paired with high-performance iridium spark plugs, this setup requires significantly less firing voltage while delivering a stronger, more focused arc. Iridium’s extremely high melting point and inherent anti-corrosive properties prevent gap widening, ensuring stable combustion, restored throttle response, and precise timing control across the entire RPM range without risking pre-ignition or spark blowout.
