Best plug for my blown application?

[LaserSVT]

OK, I done the research and it seems pretty evenly split so I will just run a poll and the winner is the ones I will buy. Let it run for two weeks and see whats what.
Need a plug to handle Texas heat and 8psi on non intercooled boost from a twin screw on my 98 Mark.
So whats best and why?


MOTORCRAFT
AWSF-22C / 1 Heat range colder - copper plug
AWSFA-12C / 2 Hea range cooler - copper plug


NGK
TR-6/ 4177/ 1 Step Colder
BP7EFS (PN - 3526) BR7EF (PN - 3346) two steps


AUTOLITE
103s / 1 heat range cooler
AR94 / 2 heat range cooler

NGK tr6

Looks like I will have to order the TR6 plugs as none of the parts shops seem to carry them.

 

[DLF]

Autolite XP103's or APP103's.

I'd run 12c's....

I run champion race plugs one step cooler on a normally aspirated higher compression with cams.

i run the ngk's on the same set up that your going for

May as well add the Motorcraft and Autolite votes together... I did my research and chose AR94s for my nitrous motor, and it's what I'd recommend for you as well. Or the 12c's since they're pretty much the same.

I think you'd be perfectly fine with any of the 2 step cooler plugs. If you drive like I do, you won't ever have a fouling problem.
