      Hi Moustafa, seems like an interesting project! Yes, this plug is 2 heat ranges colder than factory and have a non-projected tip. It works well with moderate shots of nitrous along with forced induction. I would suggest this plug for nitrous applications with approximately 175 to 225 hp jetting.
