spark plugs enhances the
performance of an engine. Acceleration is improved
when compared against normal spark plugs.

A
Does engine performance improve when
is used?
The 0.4 mm iridium center electrode and the specially shaped ground electrode
in an
enable a superior ignitability and a lower required
voltage than any seen in the past. Accordingly, there is less misfire in areas
where required voltage is high, and less misfiring in areas where firing is difficult.
No matter how heavy the conditions, high response driving is enabled. As a
result, acceleration is better than when normal spark plugs are used.
The following graph is an example of an acceleration test.

There was a difference of 0.7 seconds between
and normal spark plugs in the
time taken to reach 150 km/h. There was also a difference of 6 m in the distance covered to reach that speed.
