Description
NGK
PFR6B-11B
was
designed
specifically
for
the
TT
cylinder
head
and
is
generally
our
most
highly
recommended
plug
for
the
TT.
Gap
can
be
reduced
for
higher
boost
applications.
We
normally
recommend:
-
Stock:
~0.045"
(they
ship
pre-gapped
to
this
setting)
-
~14
psi:
0.035"
-
18-20
psi:
0.030"
For
higher
boost
pressures,
you'll
likely
need
to
bring
the
gap
down
further,
but
trial
and
error
is
often
best
here.
The
PFR6B-11B
is
the
only
plug
on
the
market
which
sits
flush
and
centers
the
electrode
in
the
combustion
chamber.
NGK
Iridiums
and
similar
plugs
will
still
run
the
car,
but
can't
produce
as
clean
of
a
burn
because
they
end
up
sunken
into
the
TT
heads.
