I decided to try out NGK Ruthenium, and it runs just as good if not better. Ruthenium is much newer technology and is supposed to be able to ignite a larger range of AFR's leading to better throttle response compared to good old iridium.

Pros: better throttle response

Mileage: 210000 km

The easiest way to know if NGK plugs are real or fake is test them for resistance.

Pros: easy to test
