NGK-R spark plugs.....or any other spark plug.....which one to choose????

I am wondering which spark plug to get for my SR20DET redtop. I am wanting to go with a stage colder than stock plug. I have a set of PFR6B-11B NGK-R plugs right now but unsure it these will work. according to NGK's website it says to use NGK PFR6B plugs so will the PFR6B11B's work?

Thanks,

PFR6B-11B are the stock plugs.

I'd go with a NGK copper in a 7 heat range.

ok thanks. Also for those that don't know then, the PFR6B-11B's are the same plugs that a 300zx Twin Turbo uses and you can get them at your local Nissan dealer. One more thing, what should I gap the plugs at?, I know for the TTZ you gap the plugs at .035 what should I gap the plugs for the SR20DET.

Thanks,

What is the part # for the copper NGK's?

PFR6B-9 are the stock s13 sr20det plugs,11 would mean the stock gap is .42 .And the stock gap is 9 which means .36.So the stock plug gap is .36
