Alright! Those babies are made right here close to
home. I'll have to try them out. In reading some of
the tests, It sure is interesting that they say the Bosch
plugs consumed 4.2 percent more fuel compared to
the Halo.

As mentioned several weeks prior to the start of the tests, Halo Spark Plug,
Inc. actually did not expect to see any differences due to the short
duration of the procedure. Our experience with HaloTM spark plugs indicates
that there is a "run-in" period that allows the engine systems to adapt to
the enhanced burning of the plug before noticeable improvements are
obtained.
Although the test only covered a period of 15 minutes, it appears that the
trend is generally improving, as the results as the test progressed were
substantially better than those at the outset. This is consistent with what
would be expected. The beginning results at 50 km/h showed a marginal 1.6 %
reduction in fuel consumption with the HaloTM plugs. This improved
dramatically at 90 km/h, where an average 6.2 % reduction was noted, with a
peak of 7.1%. The results at 120 km/h were nearly identical, with a 6.1%
average reduction, and a peak of 7.5 %.
The overall average of these three points equated to a 4.2 % reduction in
fuel consumption over the course of the test, or stated another way, the
Bosch plugs consumed 4.2 % more fuel than the HaloTM plugs. Also encouraging
is the fact that time and/or speed seemed to enhance the improvements noted
with the HaloTM spark plugs, as was predicted. If the starting results at 50
km/h are ignored (which might be justifiable when looking closely at the
data point variation noted in the HaloTM plug results. The larger disparity
might indicate that the ignition system was trying to adapt at the outset,
since the variance in the data points was nearly four times the same data
variation noted on the last cycle), then an overall average reduction of
6.15% is indicated.
Data point deviation averages were nearly identical over the course of the
entire cycle for both plugs, indicating good correlation with each run.
Ignoring the starting third of the cycle again, the HaloTM data variance
range was nearly half that of the Bosch plug, which could indicate better
performance consistency. This consistency trend was similarly noted during
the emissions testing conducted in April.
