This is a Large cutaway Parts.
Plug is replaced every 2000km with DENSO and NGK Windshield IRIDIUM alternately.
The performance is stable because they are both reliable manufacturers.
I think they are evenly matched in terms of driving performance and fuel economy. Personally, I think you can choose based on the affordability at the time.
In the case of a motorcycle, the RPM is higher than that of a car, and I think that heat is generated accordingly.
I think it's a good idea to replace it regularly with a good one because it's a Large cut Part.
