WHO IS THE HEATWAVE?

A new villain ignites beneath the hood. Meet The Heatwave. Armed with relentless temperature spikes, The Heatwave attacks where your engine is most vulnerable — your ignition coils.

WHO IS THE GLACIER?

A Villain that is Silent, Slow and Bitter.

As temperatures plunge, materials contract, resistance shifts, and brittle components are pushed to their limits. Cold starts demand more voltage and insulation begins to stiffen. Cracks form where weakness already exists.

The Glacier may freeze the battlefield — but NGK is built to power through.

BREATH OF ICE

It starts with a tiny drop of moisture.

As the sun goes down, The Glacier, the ice villain against ignition coils, breathes and the moisture turns to ice, which expands and *CRACK*, there go your ignition coils. But when the engine warms back up, those cracks become pathways for shorts, misfires, and breakdowns.

Ice may try to break through, but NGK is built to stay sealed and strong.

BUILT FOR EVERY BATTLE.

The Glacier may freeze the field. But, NGK ignition coils are built to fire when others falter.

NGK ignition coils are tested and built for sub-zero temperatures. Precision-wound windings and reinforced construction keep everything locked in place, even when the Glacier tries to pull it apart with sub-zero mornings and frozen starts.

NGK ignition coils. Built for every environment.

THE NGK DIFFERENCE

All NGK ignition coils undergo rigorous testing and quality checks throughout the manufacturing process to ensure proper fit and reliable performance.

Our verification process includes:

Validation lab testing certified to ISO 17025 for precise calibration standards
Electromagnetic interference testing to ensure the coil does not disrupt other vehicle systems
Mechanical vibration testing for durability under real-world conditions
Accelerated life testing at elevated voltages and frequencies to identify and eliminate potential failure points
