Ignition Coil & Iridium Spark Plugs for Honda CR-V (2015-2019) 2.4L

High-Performance Ignition Coil & Iridium Spark Plugs for 2015-2019 Honda CR-V (K24W / RM & RW)

Direct OEM-grade 4x ignition coil and 4x iridium spark plug kit designed to restore stable voltage output and eliminate misfires under heavy load.

The Stock CR-V Ignition System Degradation

Over tens of thousands of heat cycles, the factory ignition coils on the K24W 2.4L engine are prone to internal resistance buildup and dielectric breakdown. This progressive thermal degradation leads to weak spark propagation, hesitation during acceleration, and intermittent misfires that frequently trigger P0300-series trouble codes. Simultaneously, standard OEM spark plug electrodes experience rapid gap erosion over time, exponentially increasing the voltage demand on the already stressed coil packs. This compounding electrical fatigue ultimately results in incomplete combustion, reduced fuel efficiency, and a noticeable drop in throttle response, especially during highway merging or when the drivetrain is under load.

The Engineering Solution

This direct-replacement ignition kit resolves secondary ignition failures by combining upgraded, high-dielectric epoxy ignition coils with ultra-fine wire iridium laser performance spark plugs. The ignition coils feature advanced internal copper windings that optimize the primary-to-secondary ratio, ensuring a rapid recharge time and consistent high-voltage output even under extreme thermal conditions under the hood. Paired with the highly conductive and wear-resistant iridium center electrodes, this complete ignition overhaul is designed to ensure a concentrated, high-intensity spark. The result is a cleaner fuel burn cycle, restored factory horsepower, stabilized idle quality, and maximum resistance against spark blowout, directly addressing the core electrical weaknesses of the K-series ignition system.
