On the one hand, they will not provide any substantial extra power in series engines, and on the other hand, their life would be too short for daily travel.

But the use of racing spark plugs does make sense when permanently high speeds (>10,000 rpm) are linked with high specific power output (>100kW/l), as is the case with sport engines. Because in racing long service life is not of particular importance, the requirement is to be able to cope over a certain period of time without failing with the vibrations, thermal loads, and gas velocities arising at extremely high speeds (Formula 1 currently approx, 17 - 18,000 rpm). This is possible for the extremely cold racing spark plugs (NGK heat range 9-12) which are of a special streamlined design, preventing the "blow-out" of the spark due to turbulences of the fresh gas. Therefore, racing spark plugs are different to "normal spark plugs".
