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

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2009-2023 Nissan Murano (VQ35DE / Z51 & Z52)

Restores ignition system efficiency: Replaces degraded factory coils and worn spark plugs to eliminate misfires, stabilize idle, and restore consistent combustion across all six cylinders.

The Stock Murano Ignition Weakness

The transverse-mounted VQ35DE in the Nissan Murano creates severe heat soak conditions, particularly along the rear bank facing the firewall. Over time, this trapped thermal energy degrades the epoxy insulation within the OEM ignition coils, leading to internal short circuits and primary winding failure. Concurrently, factory spark plugs experience electrode erosion, increasing the spark gap. This widened gap forces the aging coils to generate higher voltages to bridge the arc, accelerating coil failure. The resulting weak spark causes intermittent misfires (often throwing P0300-series OBD2 codes), rough idling, decreased throttle response, and unburned fuel entering the exhaust, which can prematurely damage the catalytic converters.

The Engineering Solution

This ignition service kit corrects these thermal and electrical deficiencies by utilizing upgraded ignition coils combined with fine-wire iridium spark plugs. The replacement coils feature high-dielectric epoxy potting and reinforced housing materials to withstand the extreme underhood temperatures of the Z51 and Z52 chassis. Upgraded copper wire in the secondary windings ensures a more robust voltage output without increasing internal resistance. Paired with iridium spark plugs, which boast a significantly higher melting point than standard platinum or copper, the system maintains a precise, static gap over thousands of heat cycles. The fine-wire iridium electrode requires less voltage to fire, reducing the electrical load on the coils and ensuring a dense, concentrated spark for optimal combustion efficiency and restored power delivery.
