Ignition Coil + Spark Plugs for Hyundai Azera (2012-2017) 3.3L

Direct-Fit Ignition Coil and Spark Plug Tune-Up Kit for 2012-2017 Hyundai Azera (HG)

What it Does: The ignition coil and spark plug kit replaces worn high-voltage ignition components on the 2012-2017 Hyundai Azera to eliminate misfires, restore clean combustion, and stabilize idle quality.

The Stock Hyundai Azera Secondary Ignition Breakdown

The 3.3L Lambda II engine in the HG chassis operates under high thermal loads within a tightly packaged transverse engine bay. Over extended service intervals, factory ignition coils experience dielectric breakdown of the internal epoxy resin and silicone boots, caused by sustained thermal cycling. Concurrently, factory spark plug ground electrodes erode from spark discharge and combustion deposits, steadily widening the gap. This excessive resistance overburdens the primary windings, leading to spark blow-out under load, hesitation under acceleration, unburnt hydrocarbon build-up, and persistent P0300 through P0306 diagnostic trouble codes.

The Engineering Solution

This comprehensive tune-up kit restores factory ignition architecture by matching OE primary and secondary coil winding resistance with heavy-duty copper wire and reinforced dielectric housings that withstand extreme underhood temperatures. Matched with pre-gapped NGK Iridium spark plugs featuring fine-wire center electrodes, this package reduces the required firing voltage while delivering a hotter, more consistent spark arc. Replacing all six cylinders simultaneously mitigates uneven cylinder balance, optimizes flame kernel propagation in direct-injected chambers, and shields the primary ignition harness from damaging voltage backfeed.

What's Included

• 6 Ignition Coils replacement for UF546
• 6 NGK Iridium Spark Plugs
