The T is telling me it is a turbo plug, for a turbo head button.
Less it is special made, neither of you 2 listed came stock with a turbo head

I have no "real world" data as to which is better.
My way of thinking is. Is a Ford better than a Chevy.

I can see sealing washers on them.

RC 4T

2T = 2 stroke
4T = 4 stroke

They are four stroke glow plugs.
