By harnessing the power of Iridium, DENSO is suddenly able to shrink the surface area of the center electrode - the critical component of a spark plug. Unlike a typical platinum plug that has a 1.1mm diameter center electrode, DENSO Iridium Power plugs have the world's smallest center electrode measuring 0.4mm in diameter. This means that the voltage requirements are decreased while firing performance is greatly improved.

Built on DENSO's advanced iridium-rhodium technology and the company's decades of leadership in ignition research and development as well, DENSO Iridium Racing® plugs are components of championship caliber. Using the same basic 0.4mm center electrode configuration as DENSO's Iridium Power® plug – it's simply the best available – DENSO's motorsports plug is further enhanced with a 0.8mm ground electrode of 100 percent platinum, special insulator material with 20 percent greater strength than conventional plugs, and other valuable features for hard-core race applications. Surface-gap, recessed, and ultra-compact 8mm plugs are available for a wide range of specialized racing engines. But unlike many suppliers, DENSO doesn't offer its best stuff only to a favored few in the racing world.
