Ignition Coil and Iridium Spark Plugs for Nissan Micra (2015-2019) 1.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2019 Nissan Micra

What it Does: The ignition coil and iridium spark plug kit replaces deteriorating factory ignition components on the 2015-2019 Nissan Micra to restore peak secondary voltage, eliminate misfires, and optimize combustion efficiency.

The Stock Nissan Micra Ignition Breakdown

Under continuous thermal cycling in the compact engine bay of the K13 chassis, factory pencil coils suffer internal dielectric insulation breakdown. Over time, high ambient temperatures degrade the epoxy potting and secondary windings, resulting in intermittent high-voltage flashover, high-RPM misfires (codes P0300 through P0304), and unburned hydrocarbons contaminating the catalytic converter. Simultaneously, standard nickel-alloy or aged factory plugs develop widened electrode gaps and carbon tracking, increasing primary circuit resistance and placing excessive thermal strain on the ignition driver transistors.

The Engineering Solution

This complete tune-up kit restores reliable flame kernel development using four direct-fit pencil coils and matched iridium spark plugs. The ignition coils feature premium magnetic copper wire windings and high-dielectric silicone boots that resist thermal hardening and prevent arc-through under load. Paired with fine-wire 0.6mm iridium center electrodes and copper-core ground pins, this kit lowers required ionization voltage while offering exceptional quench resistance. The result is instant throttle response, stable idle under closed-loop fueling, and complete combustion across the entire rev range of the naturally aspirated HR16DE platform.
