Ignition Coil & Iridium Spark Plugs for Hyundai Tucson (2014-2020) 2.0L I4

High-Output Ignition Coil & Iridium Spark Plugs for 2014-2020 Hyundai Tucson (Nu 2.0L / LM & TL)

Direct-fit replacement ignition coils and iridium spark plugs engineered to restore factory combustion efficiency and eliminate persistent misfires.

The Stock Tucson Ignition Weakness

OEM ignition coils on the Hyundai Nu 2.0L engine are notorious for premature thermal degradation. Positioned directly inside the cylinder head, the factory coil packs endure severe heat cycling that gradually breaks down the internal epoxy potting. Over time, this degradation leads to micro-cracking in the housing, secondary voltage leaks, and inconsistent spark delivery. Combined with standard gap erosion on the factory spark plugs, the resulting weak electrical discharge causes incomplete fuel burn, sluggish throttle response, rough idling, and inevitable P0300-series misfire codes that trigger the Check Engine Light.

The Engineering Solution

This ignition replacement kit resolves these inherent electrical weaknesses through upgraded internal materials and optimized coil windings. The updated coils feature high-temperature silicone boots and reinforced dielectric epoxy that resist heat soak and prevent voltage bleed-over to the engine block. High-grade primary and secondary copper windings ensure a strong, consistent voltage output even under heavy engine loads. Paired with the included performance Iridium spark plugs—which boast an ultra-fine center electrode for superior ignitability and a higher thermal threshold than standard platinum—this combination ensures optimal flame kernel propagation. The precise ignition timing improves fuel atomization, stabilizes the engine idle, restores lost horsepower, and efficiently reduces unburnt hydrocarbons.
