Spark plugs are one of the most misunderstood components of an
engine. Numerous questions have surfaced over the years, leaving
many people confused.
This guide was designed to assist the technician, hobbyist, or race
mechanic in understanding, using, and troubleshooting spark plugs.
The information contained in this guide applies to all types of
internal combustion engines: two stroke engines, rotary engines,
high performance/racing engines and street vehicles.

The plug is connected to the high voltage generated by an ignition
coil or magneto. As the electrons flow from the coil, a voltage
difference develops between the central electrode and side
electrode. No current can flow because the fuel and air in the gap
is an insulator, but as the voltage rises further, it begins to
change the structure of the gases between the electrodes. Once the
voltage exceeds the dielectric strength of the gases, the gases
become ionized. The ionized gas becomes a conductor and allows
electrons to flow across the gap. Spark plugs usually require
voltage of 12,000–25,000 volts or more to 'fire' properly, although
it can go up to 45,000 volts. They supply higher current during the
discharge process resulting in a hotter and longer-duration spark.
As the current of electrons surges across the gap, it raises the
temperature of the spark channel to 60,000 K. The intense heat in
the spark channel causes the ionized gas to expand very quickly,
like a small explosion. This is the 'click' heard when observing a
spark, similar to lightning and thunder.
The heat and pressure force the gases to react with each other, and
at the end of the spark event there should be a small ball of fire
in the spark gap as the gases burn on their own. The size of this
fireball or kernel depends on the exact composition of the mixture
between the electrodes and the level of combustion chamber
turbulence at the time of the spark. A small kernel will make the
engine run as though the ignition timing was retarded, and a large
one as though the timing was advanced.
Features of Spark Plug:
1. Multi-ribbed insulator eliminate flashover.
2. 95% pure alumina provides super insulation,strong resistent to
heat shock,great mechanic and electric features.
3. Nickel plated shell prevents oxidation and corrosion.
4. Electrical heat crimping process ensures absolute gas-tight fit.
5. Inner sealing with conductive glass ensures a fine conductivity
6. Multi-layer gaskets are elasticly strong and realible in
7. Copper core electrode can prevent oxidation and corrosion,makes
it has good electric and heat conductivity ,enables the spark plug
has a long service life.
