NGK have a number of measures in place throughout the manufacturing process to ensure that all products are delivered across three key pillars: high quality, superior performance and reliability. The following measures are implemented across all NGK Ignition Coils:

1. Measured mechanically and electrically using laser guidance
2. Undergo a thermal shock and thermal cycle test that ranges from; -65 to 175 °C.
3. Tested for mechanical vibration durability, EMC and RFI compatibility
4. Endure a vacuum moulding process to ensure a blister-free encapsulation, preventing any potential electrical short-circuits

Technical features that set the NGK Ignition Coil apart from the pack include:

1. Designed to perfectly match the high performing NGK Spark Plug
2. Precise engineering for correct seating
3. Excellent pulse strength durability
4. Exceptional short-circuit and moisture resistance
5. Superior thermal loads and vibration resilience
6. Optimal dimensioning of cooling surfaces for the heat dissipation and temperature stability
