Street Thunder just tested 12 plugs in a small block chevy and the NGK G-power made the most HP and TQ About 2.5 HP and TQ better than the rappid fire
Only onle plug tested better and it's some Bosch mystery spark plug that is a surface gap plug that you won't find in the stores.
Also the retail on the NGK is 3.15 per plug
I have NGK plusg in my blown 541, LSX 440, 2 sportbikes, Supercharged Road King and my Volvo I drive everyday. Always thought they were good but did not know that they beat out 11 others
Will pick up a set for a vette next time I'm in the auto parts

I want some of those mystery spark plugs!!!
The tests seem pretty good, but there was no control test! I think the results had a decent standard deviation so they should be reproducible results... Not too much of a difference between spark plugs, but those mystery bosch spark plugs are really cool/different!!!
I like the info they gave about the melting pt of Platinum vs Iridium and that would make sense that Iridium plugs should last longer do to the higher melting point since only the tip is coated...
I guess if in a few years I cant find those Bosch "top secret" plugs then I will go with the NKG G-power...
Does anyone know anything about the Bosch "mystery"/"top secret" plugs???

These aren't Bosch, but they look very similar to the mystery plug.
