NGK Ignition Coils Review

Custom NGK ASIC Chipset

NGK ignition coils use a custom ASIC chipset designed to optimize efficiency in today’s complex ignition systems. This custom chipset ensures that the ignition coils are compatible with the latest ignition technologies, and it also helps prevent damage to the ignition components.

Extreme Condition Testing

To ensure reliability and durability, NGK ignition coils are tested under extreme conditions. Tests such as these simulate the harshest operating conditions that can occur in the real world, such as extreme temperatures, humidity, and vibration. These conditions enable NGK to identify performance issues with the ignition coils and make any necessary improvements in order to improve their performance as a result.

High-Quality Material 

The lamination on NGK ignition coils is made of high-quality electrical steel, which is able to produce the best possible spark with minimal loss of efficiency. With the use of this material, energy is saved and the magnetic field is strengthened, resulting in a stronger spark and superior engine performance as a result of reduced energy loss.

High-Grade Dielectric Thermoplastic

NGK manufactures ignition coils using high-grade dielectric thermal plastic to prevent failures caused by extreme temperature variations. The material helps protect the ignition coil from damage caused by temperature fluctuations as well as ensuring the coil’s reliability and long-lasting performance.

OEM Form, Fit, and Function

The NGK ignition coils are designed to meet or exceed OEM specifications for form, fit, and function, just like OEM coils. It is important to note that this ensures that the ignition coils are a direct replacement for the original equipment and that they will function correctly with the ignition system of the vehicle.

Validation Lab Certified to ISO17025

NGK ignition coils undergo a calibration process in a laboratory certified to ISO17025 in order to maintain calibration standards. As a result of this certification, the testing equipment used to validate the ignition coils is calibrated in accordance with industry standards, and the test results are accurate and reliable.


NGK ignition coils are tested for electromagnetic interference to ensure they do not interfere with other parts of the vehicle. Testing ensures that the ignition coils function properly. In the vehicle, the device should not interfere with other electronic components.

Mechanical Vibration Testing 

In order to ensure their reliability and durability, NGK ignition coils are subjected to mechanical vibration testing. In this test, the ignition coil will be subjected to vibrations similar to those experienced during use and this can help identify any potential weaknesses or failure points in the coil.

Accelerated Life Testing

A high voltage and frequency accelerated life test is conducted on NGK ignition coils in order to identify and correct failure points. During this testing, the ignition coils are ensured that they are reliable and durable, even in extreme conditions.

NGK Ignition Coils: Pros and Cons


  • With the NGK ignition coils, you are guaranteed to have a coil that meets or exceeds OEM specifications for look, form, and function, ensuring your ignition coils are easy to install and reliable in operation.
  • As a result of the use of NGK’s custom ASIC chipset, the ignition coil is derived from more efficient and reliable components, enabling it to provide better performance for today’s complex systems and preventing component damage.
  • It is NGK’s intention to ensure that their ignition coils are reliable and durable by testing them rigorously in extreme conditions, including mechanical vibration and an accelerated life test.
  • In the manufacturing process of NGK ignition coils, high-grade electrical steel coil lamination is combined with high-grade dielectric thermal plastic that helps prevent the coils from failing due to extreme temperature variations.
  • During testing, electromagnetic interference is observed in order to ensure the coil does not interfere with other parts of the vehicle, thereby ensuring the smooth operation of the vehicle’s electronic components.


  • The cost of NGK ignition coils may be higher than that of other aftermarket ignition coils, potentially making them less accessible to budget-conscious consumers.
  • Customers have reported compatibility issues with NGK ignition coils, although this is not unique to NGK and can happen with any aftermarket ignition coil.
  • NGK ignition coils are designed to meet or exceed OEM standards, but some customers have reported that they do not perform as well as the original equipment. It is possible, however, that this is due to issues with the installation or other factors.

Final Thought
