Notes - In the lower sample area until about
3300rpm, the K&N unit showed no
statistically remarkable gains or losses.
From there a very smooth and slightly
tapering power increase was felt
all the way to redline. Gains in the
midrange area reached about 8-
10HP, while the K&N unit drastically
reduced the 6000rpm dropoff all
the way to redline. This reduction is
responsible for the posting of the K&N
unit's highest HP gain of about 23HP
at 6500rpm.
