Because of the high cylinder pressure in a turbo engine, it is a bit
harder to light off the mixture than in a comparable normally aspired
engine. The problem is that with high cylinder pressures increased
necessary to make the spark jump the gap. This is why we run a small
of .035" or less. The higher the pressure, the higher the voltage
The platinum plugs do not have as hot of a spark, thus do not perform
high boost conditions. But, they last a really long time ! I figure,
as our plugs
are fairly easy to change - go with a cheap conventional plug, and
