Ignition Coil and Iridium Spark Plugs for Nissan Versa (2007-2012) 1.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2007-2012 Nissan Versa

Primary Function: Restores high-voltage spark energy and precise combustion timing to eliminate engine misfires, rough idling, and hesitation in 1.8L 4-cylinder powertrains.

The Stock Versa Ignition Degradation

Factory ignition coils on the MR18DE platform endure extreme thermal cycling inside deep cylinder head wells. Over time, OEM epoxy insulation deteriorates, resulting in internal copper breakdown, micro-arcing, and secondary voltage drop. Combined with standard worn electrode gaps on aged plugs, this degradation produces incomplete burn cycles, hesitation under load, poor fuel economy, and random P0300 misfire fault codes.

The Engineering Solution

This comprehensive tune-up kit features heavy-duty coil-on-plug units engineered with high-grade internal copper windings and thermoplastic housings resistant to dielectric breakdown. Paired with fine-wire iridium spark plugs, the system reduces the voltage required to jump the spark gap. The corrosion-resistant iridium center electrode maintains precise gap clearance under high cylinder pressures, delivering consistent spark propagation and crisp throttle response.
