High quality factory spark plugs for Toyota/Lexus engines 
High performance,
Long service life,
Better fuel mileage
For drivers that care about performance.
By using a 0.4mm diameter iridium alloy center electrode and a special ground electrode, IRIDIUM POWER realizes 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.

“It’s the car that I drive every day, so I want less fuel consumption.” 
For drivers that care about mileage.
If you use your car on a daily basis, you may be concerned about fuel consumption. IRIDIUM POWER is one solution.


Ignitability That's a Cut Above

With DENSO's very own U-Groove ground electrode for better spark performance
To increase ignitability, the important point is to let the flame kernel caused by the spark to grow to a large size. Normally, this can be accomplishing by widening the spark gap, however this causes spark voltage to increase, which has the opposite effect. IRIDIUM POWER uses DENSO very own U-Groove ground electrode to realize a superb ignitability while maintaining spark voltage at low levels.

Improved Horse Power(1)

Get more power with an optimal combustion cycle.
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 thus increased. The findings of a bench test using a motorcycle engine to show the improved combustion from IRIDIUM POWER is shown on the below. Compared to normal plugs, a 0.5ps (1.4%) improvement is seen in output at 110km/h.

Improved Fuel Mileage

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. Comparing a normal plug (W20FS-U) with an IRIDIUM POWER(IWF22) on a 2 cycle 50cc engine, fuel consumption improved from 41.74km/L -> 43.69km/L, an improvement of about 5%.
Note: Mileage measured using a chassis dynamo; actual driving results under normal conditions may vary.
