Ignition Coil and Iridium Spark Plugs for Nissan X-Trail (2014-2017) 2.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2014-2017 Nissan X-Trail

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces degraded factory ignition components on the 2014-2017 Nissan X-Trail to restore peak combustion efficiency, eliminate misfire codes, and re-establish smooth engine idle.

The Stock Nissan X-Trail Ignition Coil Breakdown

Mounted directly above the combustion chambers in the T32 chassis, the factory coil-on-plug units endure intense engine bay heat cycling. Over time, thermal expansion degrades the internal epoxy potting, causing micro-fracturing across the secondary copper windings. This leads to dielectric breakdown and high-voltage flashover under load. Simultaneously, factory spark plugs suffer from center-electrode erosion and gap enlargement, drastically increasing the required secondary firing voltage. The result is unburnt fuel wash, intermittent P0300 to P0304 diagnostic trouble codes, sluggish tip-in response, and accelerated catalytic converter wear.

The Engineering Solution

This complete ignition kit features four heavy-duty pencil ignition coils and four fine-wire iridium spark plugs precision-engineered for the QR25DE platform. The coils utilize high-grade magnetic steel cores, electrolytic copper windings, and advanced thermoplastic housings to resist thermal fatigue and prevent voltage leakage. Matched with laser-welded iridium electrode spark plugs featuring trivalent metal plating to prevent seizing and corrosion, this system optimizes flame kernel propagation, reduces required ignition voltage, and delivers consistent spark delivery across the entire rev range.
