What plugs are these?

NGK TR8 plugs
Motorcraft AWSFA12C
I am going to pick up some of the motorcraft to see how they are. These Denso plugs are too expensive and the insulator keeps breaking. I know, that means some detionation so I am going to switch to a cheaper plug until it is straightned out. Hopping the new 55# injectors will help.

what is the heat range of the TR8? between a TR6 and BR7? I am about to install a 4# pulley and probably will go with the BR7's, having heard a number of peoples bad luck with 4#'s + and TR6's, i just want that extra margin of safety.

The link provided by Turbobo explains the heat range. The lower the number the hotter the plug, the higher the number, the colder the plug, so a TR8 is colder than a TR6 and BR7 ...

Bye the way, I just placed an order for BR7s from Sal .. thanks for the info

What is the difference between the BR7ES and the TR6 line? I know the 7 is colder but I have been doing some researching and found that going to the BR7ES puts you in a different cross refference with the Motorcraft plug. This leads me to believe it is a different plug, even more than just how the plug is able to get rid of heat. Anyone comment on this.
Ok to fuel this information further, I jst found the plug to replace the Denso Iridum IT24 plug with an NGK R5724-8
Now I am confused

FWIW, my BR 7EFs have worked fine(except for a low rpm 'miss' that goes away at higher rpms) for 10,000 miles or more. No pinging/detonation and good power. NGK IT24s are still waiting to be installed(by the spark plug 'fairy'

BR7: (non iridium)
The B means it has a 14mm Thread Diameter
The R means it is a resistor plug
The 7 is its heat range
These plugs have a heat range of 2 through 11.
TR6: (this is an iridium plug)
The T means a 14mm diameter
The R means it is a resistor plug
The 6 is the heat range.
The iridium plugs only go from a heat range of 4 through 6. So according to the web site, there should not be a TR8 plug.
Basically both are resistor plugs, the TR6 is an warmer plug which is why it is recommended for no more than a 4 lb pulley, and the BR7 is a resistor plug that is colder and is used with pulley's bigger than the 4lber.
This is what I interpret the info at http://www.clubplug.net/ngk_sym.html

The TR6 is not an Iridium plug unless it says TR6IX. I ran the TR5IX Iridium and that's what it said. TR5 and TR6 are regular plugs. When I was looking a few months ago there was no TR6IX unles they came out with one recently.
