I originally thought of replacing it for 6W, but I didn’t expect it to be worth a lot of money to replace it in advance. A certain tiger replaced NGK94201, but it didn’t feel much after replacing it. It seems to start faster. It used to be click-boom, but now it seems to be click-boom, and the fuel consumption feeling is no different.
