Ignition Coil and Iridium Spark Plugs for Nissan Versa (2009-2019) 1.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2009-2019 Nissan Versa

Direct-replacement ignition refresh kit engineered to restore factory spark energy, eliminate cylinder misfires, and stabilize idle across HR16DE-powered vehicles.

The Stock Versa Ignition Breakdown

Factory ignition coils and standard plugs in the Nissan HR16DE engine face severe thermal degradation due to tight engine bay packaging. Over extended duty cycles, OEM epoxy insulation hardens and develops micro-fractures, while internal primary and secondary windings suffer dielectric breakdown. Paired with spark plug electrode erosion and widened gaps, this results in weak arc generation, P0300-P0304 multi-cylinder misfires, rough idle, and unburned fuel entering the catalytic converter.

The Engineering Solution

This comprehensive kit features four direct-fit coil-on-plug assemblies engineered with high-density internal copper windings and reinforced dielectric housings to resist thermal fatigue. Paired with four fine-wire iridium spark plugs, the system requires lower ionization voltage while delivering a hotter, more consistent spark under high engine load. Factory-matched blade terminals and OEM-spec keyed connectors ensure seamless integration with the factory engine harness without requiring calibration or modification.
