The
Concept
Z
Performance
Q50
&
Q60
VR30DDTT
BOV
Kit
allows
you
to
easily
install
a
pair
of
genuine
HKS
Super
SQV4
blow
off
valves,
using
our
custom
billet
aluminum
adapter
flanges,
silicone
couplers,
silicone
vacuum
lines
and
all
of
the
necessary
fittings
and
hardware.
The
kit
includes
everything
you
need
to
install
a
pair
of
HKS
SSQV4s
in
your
VR30
powered
Q50
or
Q60
with
no
additional
modifications.
Not
only
does
this
add
the
signature
HKS
SSQV
"squeal"
everyone
loves,
these
help
reduce
excess
boost
pressure
between
the
turbo
compressor
wheel
and
the
throttle
body.
From
the
factory,
the
VR30DDTT
has
no
method
of
compensating
for
compressor
surge,
which
means
excess
boost
pressure
is
forced
against
the
compressor
wheel,
this
can
accelerate
wear
on
the
turbocharger.
For
stock
boost
levels,
Nissan
has
apparently
deemed
this
to
be
acceptable
for
the
life
of
the
car,
but
once
you
crank
up
the
boost,
it's
only
going
to
get
worse.
While
we
would
like
to
point
out
that
some
factors
in
the
VR30's
design
mean
that
not
ALL
of
the
excess
boost
pressure
will
be
bled
off,
we
do
strongly
believe
that
adding
BOVs
will
help
extend
the
life
of
the
turbos,
on
both
stock
and
modified
cars.
Pre-Assembled
option
available.
We
basically
open
the
HKS
SQV
BOV
boxes,
and
install
the
flanges
in
their
correct
alignment.
This
is
useful
for
those
guys
that
don't
have
snap
ring
pliers.

Ordered on Black Friday and they arrived the following Tuesday. Super fast shipping, exactly what I ordered. 10/10
Great product, it does what it supposed to do. If you order black silicone version and it says you gotta wait months. You can give them a call to switch colors if you don't want to wait.
