I have Torquemaster plugs in my '93 NX2000, 53k miles; I didn't
notice any increase in performance, nor did performance
suffer. However, my idle did seem to smooth out a bit. They can't
hurt - they may help.

I recently installed a set of Torquemaster spark plugs. The
performance gains seem to be more than the POP charger and less
than a high flow exhuast. So I guess 3 - 5 HP. I don't have a
dyno, so the seat of the pants is the extent of the
instrumenation.
I think this is the best bang for the buck mod you can do. The
plugs cost $7.50 each or $30/set. If you assume 3 HP gain, then
the bang for the buck is $10/HP. The ECU, if you assume list
price, is $70/HP.
Torquemaster claims a 3-ish percent power gain, which translates to
about 5-ish HP. Their phone number is: (310) 322-4125. They sell
only through the factory, so you can't get these plugs anywhere
else.
The power gain seems to be in the torque / low - mid RPM range.
The car is noticably nicer in traffic and at red lights. I have
never gone over 90 MPH in my SE-R so I can't really tell about its
high end effect. Don't call me a wimp!
I also have a MSD multifire box, so my results might be better than
a stock ignition setup. The engine has a nastier roar, which I
interpret to be a faster fuel combustion rate. I can't tell about
the any improved milage because my gas foot gets heavier with every
additional engine mod. 8)
