The
Racing
Bypass
Valve
Type
34
was
specifically
designed
to
replace
the
34mm
Bosch
Bypass
Valve
used
many
OEM
applications
such
as
Nissan
and
Mitsubishi.
The
plastic
Bosch
valve
is
prone
to
failure
when
running
higher
than
stock
boost
levels.
Unlike
the
OEM
valve,
the
RBV-34
is
adjustable,
making
it
ideal
for
your
modified
vehicle.
This
RBV-34,
though
louder
than
a
stock
bypass
valve,
is
not
loud
compared
to
an
atmosphere
BOV.
