V-Line
spark plugs offer benefits down the line
NGK V-line spark plugs offer perfect ignition of the fuel/air mixture. Especially in modern low
emission lean-burn engines, even under extreme operating conditions.
Technical Advantages
NGK Spark Plugs have a very wide heat range because they utilise superior insulator matgerials and a copper
cored centre electrode. This ensures better cold starting and perfect ignition even under extreme engine
operating conditions.

Plugs for VW/Audi
NGK manufacture this type of
spark plug specially for
Volkswagen and Audi cars. Nearly
all new models can be fitted with it
(see NGK catalogue for full
listing). They satisfy the service
interval specified by the car
manufacturer.

NGK’s patented V-grooved
spark plugs
The principle is technically simple
but very effective. A V-groove is
situated in the centre electrode of
these V-Line spark plugs. This
forces the spark to occur at the
outer edge of the centre electrode
where it is easier to ignite the
fuel/air mixture.

The principle of the spark plug for
BMW is to “catch” the current
which is leaking away over the
deposits and create a spark.
Spark discharge occurs between
insulator and ground electrode.
The carbon deposits are removed
and the fuel/air mixture will be
ignited.

In addition, the voltage required to
produce a spark is reduced.
These two features give the
benefit of improved ignitability.
