Ignition Coil and Iridium Spark Plugs for Honda Accord (2013-2017) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2017 Honda Accord

What it Does: The ignition kit replaces degraded coil-on-plug units and worn spark plugs on the 2013-2017 Accord to eliminate engine misfires and restore optimal combustion efficiency.

The Stock Honda Accord Thermal Degradation & Misfire Vulnerability

The 9th-generation CR2/CR3 Accord V6 operates with tight engine bay tolerances and Variable Cylinder Management (VCM), generating severe localized heat cycles. Over time, the factory coil packs (OEM 305205G0A01, UF713) experience dielectric breakdown as the internal epoxy degrades and silicone boots harden. Concurrently, standard spark plug electrodes suffer gap erosion, dramatically increasing the required secondary voltage. This combination results in spark blowout under load, intermittent hesitation, P0300–P0306 misfire codes, and reduced fuel economy.

The Engineering Solution

This comprehensive service kit pairs six high-dielectric pencil coils with precision fine-wire iridium spark plugs designed specifically for the J35Y V6 architecture. The replacement ignition coils feature vacuum-potted epoxy insulation and high-grade copper wire windings to prevent internal arcing and maintain maximum voltage output across the entire RPM band. Paired with laser-welded iridium spark plugs, the assembly resists thermal erosion, provides lower electrical resistance, and delivers a stable flame kernel for complete fuel burn and crisp throttle recovery.
