Cross Reference
It is general question concerning DENSO SPARK PLUG that is often.
Will output and torque increase if I use Iridium Power plugs?
These are chassis dynamo test results comparing a Vitz 1300 using Iridium Power plugs and another which uses regular plugs are shown below.
With the normal plugs, the output is 98.2PS, while torque is 14.8 kgf; when this was changed to the Iridium Power plugs, the output was 99.3PS, while torque was 15.2 kgf. (This is approximately a 1.5% improvement in output.)
