Ignition Coil and Iridium Spark Plugs for Infiniti Q60 (2017-2018) 2.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2017-2018 Infiniti Q60

What it Does: Restores factory secondary ignition performance and stable combustion by replacing degraded coil-on-plug assemblies and fouled spark plugs on the 2.0L turbo engine.

The Stock Q60 Ignition Coil Breakdown and Thermal Degradation

The turbocharged 2.0L direct-injection engine operates under elevated cylinder pressures and tight thermal tolerances. Over time, OEM ignition coils suffer from dielectric breakdown in the primary and secondary insulation due to sustained engine bay heat soak. This leads to internal resistance spikes, micro-arcing, and spark blow-out under boost. Simultaneously, factory spark plugs endure center electrode erosion and gap enlargement, forcing the coils to draw excessive current, resulting in partial misfires, hesitation under throttle load, and diminished fuel efficiency.

The Engineering Solution

This comprehensive service kit pairs four heavy-duty coil-on-plug units with fine-wire iridium spark plugs designed to match exact factory ignition curves. The coils feature high-conductivity internal copper windings encased in thermal-resistant epoxy potting to resist dielectric puncture and heat degradation. Direct-fit blade terminals and robust boots ensure zero voltage leakage. The fine-wire iridium plugs provide high thermal conductivity and a focused flame kernel, requiring lower strike voltage to fire reliably in high-compression, boosted environments.
