Yep they are no better than a single electrode plug
You won't see power gains
You won't see mpg increases
It's all clever marketing and wording
What you will see is a return to the closer orginal performance and mpg of the car
Things will seem better as the old plugs are worn and not working at there best.
They will list longer though and perform on a more stable level for longer as the spark will take the shortest route to earth and this will move around the prongs as they wear down
To be fair you should of gone to a local independant as you would of got a set of plugs for around a tenner
