Default nitrous plug colder than TR6???

I'm looking for something one step colder than the TR6 with a less projected nose and a wide ground strap if possible. Anyone know of a good plug for ALOT of nitrous?
Thanks.

I am running with the NGK Racing R5724-8 Spark Plugs, three heat ranges colder than stock. You can get them at Thunder Racing

NGK makes a TR8. That's what I'm using.

Why does noone use plugs with recessed tips??
Like this (heat range 7)
http://www.ngk.com/results_cross.asp...;x=44&y=20

or this (heat range 9)
http://www.ngk.com/results_cross.asp...;x=48&y=15

I´ve heard the recessed tips are very good for Nitous as they dont stick out into the combustion chamber like standard plug.

Straps that stick out a lot (like standard plugs) are very susceptible to getting burning off with high nitrous use.

Definatly get the recessed tip. Ive melted 2 TR6's already 1 was minor and 1 was major. Lets just say the major 1 didnt have the ceramic insulator anymore.

How much power would a plug with the recessed tip and that much colder than stock hurt a car when naturally aspirated?
