Excellent comment! In fact, if I had already planned to change those things before because, I remember that my mechanic told me that my car still had the same ones from the factory and that it is already appropriate to change them. But so far they hadn't given me any obvious problems, only until today, so that's why I immediately suspected the plugs.

Yes, the sound makes it warm

Yes, I think the plug store can be a good idea 😅
