Ignition Coil and Iridium Spark Plugs for Hyundai Tucson (2010-2015) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2010-2015 Hyundai Tucson

What it Does: Delivers high-dielectric secondary voltage and ultra-precise spark timing to eliminate ignition misfires, rough idle, and combustion inefficiency across all engine loads.

The Stock Tucson Ignition Degradation

Factory coil-on-plug assemblies on the 2.4L Theta II engine suffer from continuous thermal cycling deep inside the cylinder head spark plug wells. Over time, sustained engine bay heat degrades internal secondary winding insulation and hardens silicone boots, resulting in dielectric breakdown, spark energy loss, sluggish acceleration, and engine misfire trouble codes (P0300–P0304).

The Engineering Solution

This complete refresh kit pairs four heavy-duty ignition coils featuring high-grade copper windings with four fine-wire iridium spark plugs. The coil-on-plug units use high-temp epoxy encapsulation to prevent voltage arc-through, while the laser-welded iridium plugs resist electrode erosion under high cylinder pressure, ensuring rapid flame propagation and reliable cold-start ignition.
