I think that a torque wrench works on the same pressure whatever the length of bar as when it reaches the correct torque it clicks and won't go any further.
I realise that if you use a long bar you will exert more pressure, but that just means you reach the required level quicker.

I tightened my spark plugs with a toque wrench to spec, but have been
thinking ever since that I did them too tight because: a) I oiled the
threads, which must make it easier to tighten; b) the long extender I
used must make the torque greater than the standard torque based on a short
wrench.

Subject: [W650riders] thoughts on a loud snapping sound when starting the
engine
In the past, I've read where others, including myself, have experienced
a loud snapping sound, like an electrical arcing, just after the engine
was started. When checking my valve clearances a few months back, I
discovered both of my spark plugs were little more than hand-tight from
the factory. Fortunately, even after 7500 miles, the threads looked
fine and there were no signs of leakage or damage to the threads.
At 1st, I thought maybe it was just a coincidence. But, after
approximately 5 yrs. of snapping, almost every time I fired-up the
engine cold, since tightening the plugs, I have yet to hear the
infamous snapping or arcing sound. For those of you who are
experiencing this phenomenon, if you haven't already done so, you might
check your plugs.
