At the moment the spark jumps
the gap it causes a high frequency burst of energy, this
is known as RFI (radio frequency interference). This is
why resistor spark plugs were introduces in the mid 1960's.
Placing a resistor within the spark plug suppresses the
RFI. As well as reducing RFI for radio, television and
mobile telephones etc, many modern ignition systems require
resistor plugs to stop RFI from interfering with the vehicle's
on-board electronic control units (ECUs).If non-resistor
plugs are used in place of resistor ones, the result can
be malfunction and in some cases immobilisation of the
vehicle. So Resistor spark plugs should always be fitted
AGA Resistor spark plugs feature:
1. Using the Resistor powder as Row material.
Now in the
world, there are only two kind of Resistor place within
the spark plugs line. One is resistor block, For example
NGK, the other is resistor powder. For example, Bosch,
Eyquem ,AGA. The resistor block., is short and value of
resistant is stabilization, but seal-ability of spark
plugs is worse than using the resistor powder. Resistor
powder is placed in between inner-seal material. under
very high Temperature, the Resistor powder will be soft
as chutty and together with inner-seal. Pass the terminal
pressing and coldness, the resistor powder will be solidify.
So resistor powder not only as a resistor but also as
a inner-seal within the resistor spark plugs.
2. More safety
AGA resistor spark plugs ,the resistant
range between 3000 ohms and 12000 ohms, the resistant
value down when the temperature up.
3.resistor length only 7mm
resistor length in spark plugs is only 7mm, so we can
using resistor powder as material to make the good quality
bantam spark plugs, For example ,AGA L7RT,L6R...
