Q
Blow

Valve
is
a
newer
version
of
the
original
50mm
BOV.
Featuring
an
improved
design
through
countless
hours
of
R&D,
Tial
was
able
to
increase

the
original
design.
This
is
now
believed
to
be
the
highest
flowing
on
the
market.

from
6061
aluminum
alloy
with
a
50.5mm
valve
and
V-band
clamp
mounting,
this
new
version
just
got
better.

Customer Questions
Question:
How do you determine which spring is right for your car?
- Justin
Answer:
Hi Justin, you generally want the BOV spring a little bit weaker than however much vacuum your car pulls at idle and/or with the throttle closed. This ensures that when you let off, the vacuum created by your engine will overpower the spring and force it open.
