Description
For
2013-2016
Nissan
Altima.
The
first
step
in
upgrading
your
car's
performance
is
to
replace
the
restrictive
stock
air
box
with
a
STILLEN
Hi-Flow
Intake.
Additional
air
flow
increases
the
engine's
efficiency
and
power
output
by
increasing
the
quantity
of
the
air/fuel
ratio.
The
STILLEN
Hi-Flow
consists
of
a
precision
machined
ring
and
a
gauze
element
(cleanable)
filter.
Like
a
velocity
stack,
the
ring
uses
the
venturi
effect
to
accelerate
air
intake
speed.
Power
and
throttle
response
will
improve
throughout
the
entire
RPM
range.
Your
best
dollar-per-horsepower
investment
by
far!
Most
people
find
the
authoritative
note
of
the
intake
pleasing,
but
note
that
increased
noise
levels
result.
With
CARB
approval,
most
STILLEN
Hi-Flow
Intakes
are
50
state
legal.
Clean
your
filter
regularly
for
best
results.
