As the name implies, state of the art laser welding procedures are used
in the manufacturing of NGK Laser Platinum Spark Plugs. These spark plugs
are manufactured to the rigorous demands of OEM car makers and modern service
length requirements. Among the features of the NGK Laser Platinum Spark Plug are:
Lasers are used for pinpoint precision welds, reducing excess debris.
The reduction of debris decreases the required voltage to bridge the spark gap.
Platinum tips welded on the ground and center electrodes reduce the wear
rate on both of these surfaces.
