Ignition Coil and Iridium Spark Plugs for Hyundai Veloster (2019-2021) 1.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2019-2021 Hyundai Veloster

Direct Replacement Ignition Service Kit: Restores factory secondary ignition voltage, prevents boost-induced spark blowout, and ensures complete flame propagation across all four cylinders.

The Stock Veloster Secondary Ignition Breakdown

Direct-injected turbocharged engines subject ignition coils and spark plugs to elevated combustion pressures and rapid thermal cycling. Over time, OEM coil pack epoxy potting degrades under thermal stress, causing dielectric breakdown, micro-arcing, and intermittent misfires under load. Simultaneously, standard spark plug electrodes erode and widen the gap, placing excessive electrical strain on the primary windings and triggering P0300-P0304 fault codes during peak boost.

The Engineering Solution

This ignition overhaul kit features heavy-gauge internal copper windings sealed in high-dielectric epoxy housing to eliminate internal voltage leakage and resist engine bay heat soak. The matched fine-wire iridium spark plugs lower the required firing voltage, provide exceptional thermal conductivity, and resist carbon fouling, ensuring crisp throttle response, stable idle, and uniform direct-injection combustion.
