Ignition Coil and Iridium Spark Plugs for Infiniti M35 (2006-2008) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2006-2008 Infiniti M35

What it Does: Replaces degraded coil-on-plug packs and worn plugs to eliminate engine misfires, erratic idle, and unburnt hydrocarbon emissions across the VQ cylinder bank.

The Stock M35 Ignition Breakdown

Prolonged heat cycling inside the crowded VQ35DE engine bay causes the factory epoxy insulation and internal copper windings to deteriorate. Over time, high thermal loads induce micro-fractures in the coil casing, causing secondary voltage leakages, spark blowout under load, and intermittent P0300–P0306 DTC faults. Compounded by standard spark plug electrode erosion, combustion efficiency degrades significantly.

The Engineering Solution

This direct-replacement ignition kit features six reinforced coil-on-plug units wound with high-grade internal copper wiring and housed in thermal-resistant composite casings for superior dielectric strength. Paired with six fine-wire iridium spark plugs featuring high-melting-point electrodes, this setup guarantees precise spark timing, rapid flame kernel propagation, and zero arc tracking under high thermal stress.
