Compared to conventional plugs, G-Power delivers better starts, superior acceleration and greater fuel economy.

Due to the fine central electrode (0.6mm) made of a new material, iridium alloy, we improved ignitability, starting performance, and acceleration performance.

The plug has excellent durability, because an iridium alloy chip made from extra-fine new material, is used for the central electrode (0.6mm) and a platinum alloy chip is used for the ground electrode.  It also has a high ignitability and helps reduce discharge voltage.

For further improvement of the ignitability of the conventional iridium plugs, a needle-shaped Platinum chip is welded to the leading edge of the ground electrode to thereby curb the flame damping ability of the base material of the electrode. This has ensured the durability of the plug and has also improved the ignitability to the maximum.
