In addition, in April 1997, to respond to high-output, low-fuel consumption and low-emissions needs of recent years, the world's first automotive durable iridium plug was developed, and delivery to carmakers started. Then, in April 1998, this technology was applied to develop IRIDIUM POWER the world's first and world's finest 0.4mm iridium center electrode for the car aftermarket.

The high performance possible only from the 0.4mm dia. Iridium center electrode and the astounding durability of DENSO's patented iridium alloy was a sensation in the aftermarket field. Consumers were now able to experience the sense of acceleration unavailable from plugs up until then.

Now it's possible for you to use IRIDIUM POWER and give yourself with a ride that you've never experienced before.
