Ignition Coil + Spark Plugs for Hyundai Sonata (2006-2007) 2.4L

Direct-Replacement Ignition Coil & Spark Plug Kit for 2006-2007 Hyundai Sonata (NF)

What it Does: The Ignition Coil and Spark Plug Kit restores primary combustion efficiency, stabilizes idle, and eliminates misfires on the 2006-2007 Sonata 2.4L by delivering consistent high-voltage current directly to the combustion chamber.

The Stock Hyundai Sonata Ignition Breakdown

Factory coil-on-plug modules on the NF chassis endure punishing thermal cycling seated directly atop the cylinder head. Over continuous engine cycles, factory internal epoxy breaks down, causing dielectric leakage and primary-to-secondary winding shorts. Coupled with gradual electrode erosion on aged factory plugs, the resulting increased spark plug gap demands excessive secondary voltage, accelerating coil driver burnout and producing erratic hesitation under load.

The Engineering Solution

This coordinated service kit pairs high-dielectric replacement coils with NGK Platinum spark plugs to refresh primary ignition performance. Built to match UF546 specifications, the coils feature temperature-resistant epoxy potting and robust silicone boots that isolate secondary voltage and eliminate spark scatter. The fine-wire platinum core electrodes resist thermal degradation and carbon fouling, maintaining a stable arc gap across the entire G4KC powerband for crisper throttle response and complete fuel burn.

Frequently Asked Questions & Fitment Warnings

Does this fit the NF Sonata?

Yes, this is a direct fit for the 2006-2007 Hyundai Sonata equipped with the G4KC 2.4L engine. This kit is not compatible with 3.3L V6 models or universal ignition applications.

Are spark plug wires included with this kit?

No, this application uses an individual coil-on-plug setup, meaning plug wires are not required or included.

The Hyundai Reliability Standard

Engineered to deliver OE-caliber durability for daily driving, this matched ignition package ensures smooth idle stability and long-term powertrain reliability without causing false misfire codes or diagnostic check-engine lights.
