Ignition Coil and Iridium Spark Plugs for Hyundai Tucson (2016-2018) 1.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2016-2018 Hyundai Tucson

Primary Function: Restores factory secondary ignition output and precise spark timing to eliminate engine misfires and erratic idling under boost.

The Stock Tucson Thermal Breakdown

The turbocharged 1.6L Gamma T-GDI engine subjects factory coil-on-plug modules to intense cylinder head thermal cycling and high combustion chamber pressures. Over time, the internal epoxy potting degrades, leading to dielectric breakdown, secondary winding micro-arcing, and spark blowout under load. Concurrently, factory standard plug electrodes experience gap erosion from direct-injection cylinder pressures, leading to sluggish throttle response, elevated hydrocarbon emissions, and intermittent P0300-series trouble codes.

The Engineering Solution

This replacement ignition overhaul kit features coil assemblies manufactured with high-conductivity copper primary and secondary windings insulated by heavy-duty dielectric resin to resist heat soak. Direct-fit blade terminals ensure low electrical resistance at the factory wiring harness. Paired with fine-wire iridium spark plugs, this kit provides a concentrated, high-energy spark kernel capable of withstanding forced-induction cylinder pressures, ensuring complete flame-front propagation, stable idle, and immediate transient response.
