Ignition Coil and Iridium Spark Plugs for Hyundai Elantra (2011-2016) 1.8L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2011-2016 Hyundai Elantra

Primary Function: Restores factory secondary ignition output and combustion efficiency across all four cylinders to eliminate misfires and irregular idle.

The Stock Elantra Ignition Degradation

Factory coil-on-plug assemblies in the 1.8L Nu engine are subjected to extreme thermal cycling deep within the cylinder head spark plug wells. Over time, OEM epoxy insulation degrades and internal windings develop micro-fractures, while standard plugs experience gap erosion. This dielectric breakdown increases electrical resistance, causing weak spark discharge, erratic cold-start idling, hesitation under acceleration, and unburned fuel dumping into the exhaust stream.

The Engineering Solution

This comprehensive service kit features direct-fit coil packs built with premium-grade internal copper windings and reinforced thermoplastic housings to resist thermal fatigue and prevent high-voltage arcing. Paired with high-melting-point fine-wire iridium spark plugs, the system ensures lower voltage requirement for spark gap ionization, providing a robust flame kernel, stable idle, and maximized fuel atomization across the entire operating RPM range.
