While
it
is
true
that
the
stock
airbox
system
on
the
GTR
is
excellent,
through
careful
testing
we
were
able
to
develop
a
system
that
adds
significant
mid-range
torque
and
horsepower
while
improving
boost
response.
The
Harman
Motive
Intake
System
draws
cool
air
by
placing
large
conical
filters
inside
the
front
bumper.
It
completely
replaces
the
stock
airboxes
and
MAF
housings.
The
primary
parts
of
the
Harman
Motive
Intake
System
are
the
billet
MAF
housings.
Designed
and
machined
in-house,
our
housings
replicate
the
stock
system
size
with
high
accuracy.
This
allows
our
intake
to
function
without
any
adjustments
to
fuel
trims
or
full
throttle
air/fuel
ratio.
As
such,
our
intakes
will
work
with
the
stock
ECU
or
any
tuning
designed
for
the
stock
airboxes.
Installation
requires
removal
of
the
front
bumper.
The
Nissan
bumper
is
well
made
and
easy
to
remove/install.
No
cutting
or
permanent
modifications
are
required
for
the
installation
of
this
intake
system.
The
Harman
Motive
intake
sounds
incredible
on
the
GT-R.
By
placing
the
filters
outside
the
engine
bay,
air
induction
and
bypass
(blow-off
valve)
can
be
heard
during
aggressive
acceleration
and
shifting.
However,
the
intake
is
quiet
during
cruise
and
does
not
have
an
annoying
"sucking"
sound
during
normal
driving.

On
the
dyno,
Harman
Motive's
intake
system
made
+8WHP
and
+18TQ
while
improving
spool
by
300rpm.
All
testing
was
performed
on
the
same
car
on
the
same
day,
they
never
removed
the
car
from
the
dyno.
Tests
were
performed
with
the
hood
closed
and
the
vehicle
fully
warmed
up.
You
can
see
a
decrease
in
intake
temperatures
throughout
the
run
with
the
Harman
intake
-
an
impressive
result
given
the
excellent
engineering
of
the
stock
airbox.
