Ignition Coil and Iridium Spark Plugs for Nissan Sentra (2013-2019) 1.8L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2013-2019 Nissan Sentra

What it Does: Restores factory secondary ignition voltage and combustion efficiency by replacing degraded coil-on-plug assemblies and fouled spark plugs with high-grade copper windings and fine-wire iridium plugs.

The Stock Sentra Secondary Ignition Breakdown

The factory ignition coils on the MRA8DE engine routinely suffer from thermal fatigue and dielectric breakdown due to intense under-hood cylinder head heat cycles. Over time, internal epoxy insulation deteriorates, resulting in micro-arcing, secondary resistance variations, and high-rpm spark blowout. Coupled with eroded standard plug electrodes, this leads to hesitation under load, erratic idle oscillation, reduced thermal efficiency, and intermittent P0300-P0304 misfire codes.

The Engineering Solution

This comprehensive service kit pairs four heavy-duty coil-on-plug packs with four matched iridium spark plugs. The ignition coils feature high-conductivity internal electrolytic copper windings paired with high-temperature epoxy potting to resist thermal cycling and electrical leakage. The iridium plugs offer a low-voltage-demand, laser-welded center electrode that ensures stable flame kernel propagation, superior anti-fouling characteristics, and consistent dielectric strength under high compression.
