Rimfire
Long Reach
Spark
Plugs
 
These
are the new
Rimfire brand
Long Reach
1/4-32 spark
plugs by Paul
Knapp. On many
engines, the
regular reach
plugs don't
allow the
spark gap to
be as close to
the
combustion
chamber as it
should be.
These not only
put the spark
closer
to the
combustion
chamber, but
because the
porcelain
insulator
inside
the body is
longer, the
plug will run
a little
hotter and
cleaner. I am
sure these
will make a
lot of model
engines run
better than
ever.
Rimfire plugs
have ceramic
insulators and
the ground
strap is part
of
the body, not
an add on that
can fall off.
The plugs are
1.080" overall
length and
they are .350"
long from
under the body
to and
including the
ground strap.
The plugs come
in a nifty
little screw
cap vial.
They came with
(2) copper
gaskets when
the photo was
taken, but
since
then they come
with just (1)
copper gasket
(.031" thick)
, which is all
that is needed
anyway.

NGK CM-6 Spark
Plug
 
NGK
traditional
plugs are
constructed
for longer
life and
optimum
performance.
Corrugated
ribs prevent
flashover. NGK
uses only the
purest alumina
silicate in
its ceramic
insulator
which
give all NGK
plugs greater
strength and
better heat
transfer.
Copper
cored and
triple sealed
to further aid
in heat
removal and
prevent
interior
leakage.

Spark Plug
Wire
30
inch length of
1/8" diameter
high voltage
ignition wire. If
your coil does not come with a high voltage spark plug wire, we
recommend using this high voltage wire from the coil to your spark
plug, and for 4-wire coils, from the coil to the engine ground as well.
Failure to use a high voltage wire risk shorting your spark plug
through adjacent wires (yes - a spark can jump through wire insulation)
and possibly damaging other ignition components.
