DENSO has been setting the standard for spark plug technology since 1959. They develop all of their ranges in-house, and manufacture them in their own ISO9000 certified factories worldwide - with 'zero defects' as standard. They also provide this outstanding OE quality to the aftermarket. Including Standard, Platinum and Iridium, DENSO Spark Plugs cover a complete range of continually updated references. Guaranteeing optimum engine performance, choose DENSO Spark Plugs for every automotive, motorcycle, marine and small engine application.

DENSO's Iridium Power Spark Plugs bring all the benefits of iridium technology to the mainstream motorist. Whatever type of car you drive - DENSO's Iridium Power Plugs are extremely tough and wear-resistant, with superb ignitability. Responding to increasingly strict European emissions legislation and the rising cost of petrol, another important benefit for motorists is that Iridium Power Plugs can improve fuel economy by up to 5% compared to standard plugs.

Iridium Power is recommended for drivers who care about:

  • Performance
    By using a 0.4mm diameter iridium alloy centre electrode and a special ground electrode, Iridium Power realises spark performance unseen until now. It steadily gives a high level of response under a variety of driving conditions. The result? Increased acceleration and torque compared to regular plugs.
  • Mileage
    If you use your car on a daily basis, you may be concerned about fuel consumption. Iridium Power is one solution. Even during idling ignition is assured, with less fuel consumption and less noise. The good ignitability from the fine electrode (0.4mm) of Iridium Power draws out much more performance from the engine.
  • Horse Power
    Iridium Power has a low required voltage and a high ignitability, resulting in less misfiring and no spark, the outcome being a dramatic improvement in combustion. Engine output is therefore increased.
  • Acceleration
    Iridium Power best demonstrates its performance improvement during acceleration. Iridium Power has a 0.4 mm diameter iridium centre electrode and a specially shaped ground electrode. These features combine to achieve higher ignitability and require lower spark voltage than ever before. This enables high-response driving with fewer misfires than under higher required voltage spark conditions, and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.
