Ignition Coil + Iridium Spark Plugs for Nissan Frontier (2001-2004) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2001-2004 Nissan Frontier

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores complete secondary ignition voltage and consistent flame kernel propagation on the 2001-2004 Frontier to eliminate cylinder misfires and rough idling under load.

The Stock Nissan Frontier Primary Ignition Breakdown

The aging factory ignition hardware on the KA24DE platform is prone to thermal fatigue and dielectric breakdown. Constant underhood heat cycling degrades internal epoxy insulation and primary windings inside the coil, leading to carbon tracking, secondary voltage leaks, and intermittent misfires under heavy throttle. Simultaneously, high-mileage copper or worn platinum plugs develop widened electrode gaps that demand higher firing voltage than degraded coils can provide, choking off combustion efficiency, fouling catalytic converters, and triggering P0300 through P0304 fault codes.

The Engineering Solution

This service kit resolves weak spark events by pairing a heavy-duty direct replacement ignition coil with precision fine-wire iridium spark plugs. The ignition coil features high-dielectric epoxy potting, thermal-resistant magnetic core laminations, and reinforced primary/secondary copper windings designed to resist internal insulation breakdown. Matched with fine-wire iridium electrodes requiring lower strike voltages, this assembly provides instantaneous arc initiation, superior quenching resistance, and high resistance to spark wash during high-load hauling conditions. Replacing these components as a matched unit stabilizes dwell time and maintains stoichiometric combustion efficiency across the entire RPM band.
