Spark Plugs

Worlds smallest centre iridium electrode of 0.4mm diameter

With a strong reputation for quality, DENSO spark plugs guarantee optimum engine performance for automotive, motorcycle, marine or small engines.

For decades, DENSO spark plugs have been used as Original Equipment (OE) by many major automotive and motorcycle manufacturers including Ford, Honda, Kawasaki, Lexus, Mitsubishi, Subaru, Toyota and Yamaha.

In 1972, DENSO received a patent for the innovative U-groove ground electrode design which later became the industry blueprint for spark plug manufacture (see history). In the 1980s, DENSO became the first company to mass produce the double-platinum spark plug.

Today, DENSO continues to push the technology barrier toward the horizon. Our latest achievement, the Iridium Power® Performance range, truly redefines performance driving with the worlds smallest iridium alloy electrode diameter of 0.4mm.

  • Improved cold-starting.
  • More efficient fuel consumption.
  • Better engine performance and acceleration.
  • Smoother idling performance and throttle response.
