Ignition Coil and Iridium Spark Plugs for Infiniti I30 (2000-2001) 3.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 2000-2001 Infiniti I30

Primary Function: Restores factory secondary ignition performance, eliminates primary/secondary circuit misfires, and stabilizes combustion efficiency across all six cylinders on the 3.0L V6 platform.

The Stock I30 Thermal Breakdown and Secondary Arc Failure

The transverse engine bay layout of the A33 chassis places the rear cylinder bank in a high thermal zone with limited passive cooling. Over heat-soak cycles, factory epoxy and internal insulation break down, leading to dielectric punch-through, inter-winding shorts, and low secondary voltage output. Paired with aged spark plug electrode gap erosion, high resistance triggers intermittent P0300–P0306 DTC misfires, unburnt hydrocarbon build-up, and rough idle under load.

The Engineering Solution

This comprehensive tune-up kit features six coil-on-plug units engineered with high-grade copper windings, high-dielectric epoxy potting, and reinforced thermoplastic housings to resist thermal fatigue. The included fine-wire iridium spark plugs feature low voltage requirement thresholds, high thermal conductivity, and anti-fouling ceramic insulators, restoring precise ignition timing and full flame kernel expansion.
