Ignition Coil and Iridium Spark Plugs for Nissan Cube (2009-2014) 1.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2009-2014 Nissan Cube

What it Does: Restores precise secondary ignition voltage and combustion efficiency across all four cylinders to eliminate misfires, rough idle, and poor fuel economy in the 1.8L engine.

The Stock Cube Thermal Degradation and Voltage Leakage

Factory ignition coils on the MR18DE engine endure severe thermal cycling within the tight, enclosed spark plug wells. Over time, heat soak degrades the internal epoxy resin and insulation around the primary and secondary copper windings, causing micro-arcing and internal resistance breakdown. Concurrently, standard OEM spark plugs suffer from electrode erosion and gap enlargement, requiring higher breakdown voltage that overburdens aging coil packs and triggers P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This complete tune-up kit pairs heavy-duty coil-on-plug assemblies with fine-wire iridium spark plugs. The ignition coils feature premium-grade internal copper windings and high-dielectric silicone boots that resist dielectric breakdown under sustained operating temperatures. Paired with laser-welded iridium electrode spark plugs, this setup lowers required firing voltage, provides a consistent spark kernel, prevents blow-out under load, and optimizes flame front propagation across the combustion chamber.
