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.

forces the spark to occur at the

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.
