Ignition Coil and Iridium Spark Plugs for Honda CR-Z (2011-2016) 1.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2011-2016 Honda CR-Z

Primary Function: Restores factory secondary ignition voltage and combustion efficiency across the entire RPM band by replacing worn ignition coils and degraded spark plugs.

The Stock CR-Z Ignition Degradation and Thermal Breakdown

The compact engine bay of the LEA hybrid engine subjects coil-on-plug boots to continuous high thermal cycles. Over time, internal epoxy insulation breaks down, leading to micro-arcing, secondary resistance increase, and high-load misfires. Simultaneously, factory spark plugs suffer center electrode erosion and gap expansion, straining the Integrated Motor Assist (IMA) powertrain transition and causing rough idle, hesitation, and reduced fuel economy.

The Engineering Solution

This comprehensive tune-up kit features heavy-duty replacement coils wound with high-grade copper primary and secondary windings encased in premium dielectric potting to eliminate internal shorting. Paired with fine-wire iridium spark plugs featuring laser-welded tips and trivalent metal plating, this setup delivers consistent spark energy, high resistance to fouling, and precise thermal conductivity across all driving modes.
