It is a question concerning the IRIDIUM POWER that is often.
What happens to fuel consumption when IRIDIUM POWER is used?
In many cases, fuel consumption is improved.
When spark IRIDIUM POWER plugs are used, accidental fire and misfiring rarely occur under various driving conditions. Therefore, combustion is extremely good. In turn, a healthy engine can be maintained and fuel consumption is improved.
In the idling examples given in the answer to , combustion improved and therefore the revolution count increased. However, if the enginefs idling revolution control is operated, control that returns an increased revolution count will be operated and the throttle constricted, thus improving fuel consumption during idling.

The following graph is the comparison of fuel consumption during idling.
Test engine: 1600 cc 4-valve 4-cylinder
(The above is analyzed in DENSO.)
In many cases, fuel consumption will also improve for the same reason during actual running.

The following graph is an example that shows an improved fuel consumption when a car is being driven at 60 km/h on flat ground.
Test engine: 1600 cc 4-valve 4-cylinder
(The above is analyzed in DENSO.)
