More power and better response at the twist of the throttle!

DENSO Iridium Power spark plugs provide motorcycle enthusiasts with the ideal combination of increased power and reduced fuel consumption, making them an incredibly cost-effective way to liberate more from their machines.

The freedom of the open road is one of the aspects that motorcyclists most appreciate, but being able to enhance that liberty with better response and greater efficiency from their machine, is an added value benefit that takes an enjoyable experience to a new level.

Although most riders may pay little attention to the spark plugs fitted in their machines, the realisation that they can make a marked difference in the way their motorcycle performs, should make them think again.

Upgrading from standard, to DENSO Iridium Power spark plugs, is a simple and effective way to liberate more power from the engine, without major cost, or the complication of engine tuning or remapping. However, the benefits don’t end there because not only do Iridium Power generate more power from the engine by optimising the combustion cycle, the ignition process is also improved, which delivers greater fuel efficiency and reduced consumption, meaning they can go further, faster, on a tank of fuel.

Delving into detail, key to the performance characteristics of DENSO Iridium Power spark plugs is the patented, ultra-fine 0.4 mm diameter iridium alloy centre electrode, which, despite requiring lower voltage, improves the engine’s firing performance. The opposite ground electrode is produced with a U-groove cut into its inside face and this provides a larger volume of space for the flame to form and the additional edges further reduce the voltage required to produce the spark. This technology optimises firing performance, without increasing the spark gap, which can have negative repercussions.

Delving into detail, key to the performance characteristics of DENSO Iridium Power spark plugs is the patented, ultra-fine 0.4 mm diameter iridium alloy centre electrode, which, despite requiring lower voltage, improves the engine’s firing performance.

This technology optimises firing performance, without increasing the spark gap, which can have negative repercussions.

In addition, the tip of the ground electrode has been shaped to form a taper, which reduces the area that comes into contact with the flame, as well as its mass, and this cuts vibration and decreases the heat load it is subjected to, meaning it can cope with heavier load condition riding.

Another significant advantage that DENSO Iridium Power spark plugs provide owners is their considerable lifespan, which at 60,000 km means that they will also outlast traditional alternatives and so increase the time they can savour the freedom of the open road.
