Powerdyne 6#Users, what plug?

Do most of you guys running PD 6# use the NGK TR6, or are you going 2 steps colder? Thanks.

I would recommend going with a NGK TR6 or an Autolite 104 plug.

Yep... TR6's are good but, usually have to order them at the parts store. Gap around 0.035". 104's are good too and usually around $1 at just about any local auto store.

I run NGK TR5's gapped at 0.035".

Later ... Larry S.

I'm running the autolite 104 as well

Nobody uses Champion plugs anymore? I always use RS12YCs and I might go down to an RS9YC this summer. I had TR5s in my car but they kept fouling out anytime I was on the transbrake and the 2 step.
