The Science of Performance

Demand Performance, Choose NGK.
For drivers demanding performance, the experts at NGK have delivered an edge with the Iridium IX Spark Plug.

The use of iridium in spark plugs, allows for a dramatically smaller centre electrode diameter (CED) of 0.6mm compared to a standard nickel alloy spark plug.

This enables a reduced quenching effect, resulting in high ignitability and increased power, allowing you to squeeze that last bit of performance out of your engine.
