The 0.4mm 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.
Vehicle: 2000cc 4cyl 4-cycle
Operating condition: Creep (2nd) -
> Full Open (100km/h)
Normal spark plug ( 2.5)

There was a difference of 0.08 seconds between
and normal spark plugs in the time taken to reach 100km/h.
