The Viper
series are the world's smallest commercially
available spark plugs. The Z1 was originally
engineered to meet the demand for high-tension
miniaturization necessary to build smaller
V8s, V10s, and V12s. As we build smaller and
smaller engines the need for smaller spark
plugs is unavoidable. Vipers were designed
produce a hot spark and fit within the
confines of our micro-creations- while
maintaining scale effect.
The Z1 is the
longest of the series with its insulator
designed for the higher voltage systems and a
deep reach for clean operation. The long
insulator is perfect for multi- cylinder
engines where the spark plugs must be
significantly recessed into the head. It burns
hot and is an excellent choice for both high
performance and low performance engines.
Sometimes the
same performance is required, but from a plug
that would be a little more aesthetically
pleasing from the scale effect. The Z2 has a
shorter insulator outside, but retains the
same deep reach and internal features as the
Z1. It will maintain the same operating
characteristics as the Z1, but in many cases
may look more realistic in smaller engines.
The Z3
utilizes the same insulator outside as the Z2,
but has a shorter reach. It will perform as
well as the Z1 and Z2, but accommodates those
engines that do not need a deep reach or do
not have the head thickness for longer
threads. Although it appears to be a cooler
plug don't let this one fool you. It has been
used extensively in both high performance and
low performance engines and it performs
flawlessly for many, many hours at a time.
We discovered,
in most cases, the shorter outer insulators in
this series would operate at the same higher
voltages without shorting to ground outside of
the engine. Many of the Z3 plugs are operating
on very high voltage CDI systems without
shielding. This will vary depending on the
proximity of the metal surrounding your plug
however.
