The
GKTECH
high
performance
engine
fan
has
been
designed
and
engineered
in
Australia
with
the
intention
of
pulling
more
air
than
the
factory
item.
When
tested
on
a
dyno
the
GKTECH
high
performance
fan
took
less
than
half
the
time
to
cool
down
from
90
degrees
to
operating
temperature
(good
for
next
time
you're
on
the
start
line
at
the
track).
Super
easy
to
install,
simply
remove
your
factory
fan
(4
bolts)
and
install
the
new
fan,
it
is
a
direct
replacement
clutch
fan
to
suit
SR,
KA,
RB,
VG
engines
An
adapter
is
needed
to
fit
RB/VG
engines,
as
seen
here: RB/VG

-
Direct

of

NOTE:
Can
NOT
be
used
in
conjunction
with
Nismo
engine
mounts
on
an
S13/180sx
as
the
mounts
raise
your
motor
approximately
0.78"
(20mm)
which
will
make
our
fan
hit
your
radiator
shroud
(our
fan
is
0.59"
(15mm)
larger
in
diameter
than
the
OEM
SR20
fan)
however
S14/S15’s
with
Nismo
engine
mounts
are
fine
and
our
fan
will
fit.
FAQS
What's
the
advantage
of
having
more
air
flow?
We
tested
the
clutch
fan
on
a
test
vehicle
in
a
controlled
environment
(on
a
dyno)
with
back
to
back
tests
and
from
194
degrees
fahrenheit
it
took
less
than
half
the
time
to
go
from
194
degrees
fahrenheit
to
idle
operating
temperature.
Will
this
fit
my
car?
Please
refer
to
the
confirmed
vehicle
list
in
the
item
description.
We
do
not
sell
any
items
that
aren’t
listed
on
our
website
and
if
we
haven’t
confirmed
fitment
on
your
car,
then
we
don’t
know
if
it
will
fit
or
not.
Please
do
not
ask.
How
do
clutch
fans
compare
to
thermo
fans?
If
you've
ever
been
to
the
track
with
thermo
fans
you
know
that
unless
setup
with
a
shroud
and
setup
correctly,
they're
useless.
Clutch
fans
with
the
standard
shroud
are
the
way
to
go.
What's
the
weight
on
the
clutch
compared
to
the
standard
item?
The
standard
clutch
fan
is
16.33''
in
diamter
and
weighs
in
at
1.41lbs.
Our
new
design
is
16.92''
in
diameter
and
coincidentally
also
weighs
1.41lbs.
What
is
the
clutch
fan
made
of?
The
clutch
fan
has
a
metal
center
(like
the
factory
unit)
and
is
made
of
ABS
plastic
(like
the
factory
unit).
Will
I
lose
any
engine
power
with
the
fan
pulling
more
air?
No,
with
our
dyno
tests
on
the
same
car
within
30
minutes
of
each
test
with
multiple
runs
made
we
actually
GAINED
around
1%
in
power
with
the
new
clutch
fan
installed.
The
cause
of
this?
There
was
less
heat
soak
and
everything
was
running
cooler.
This
all
sounds
too
good
to
be
true!
This
isn't
rocket
science
but
we'll
let
you
be
the
judge.
Try
it
out,
guaranteed
100%
it'll
blow
you
away
(see
what
we
did
there!
ha!).
But
seriously,
this
is
one
of
our
favourite
products
and
before
you
go
any
buy
any
other
cooling
related
parts,
this
is
the
one
that
will
make
the
biggest
difference.
Which
way
do
I
install
it?
The
fins
on
the
fan
are
to
taper
back
towards
the
engine.
Can
be
used
with
older
discontinued
adapter:
RBXX-ADPT
for
RB/VG
