It does work if your old plugs are worn. After 18k the electrodes on mine were pretty eroded. Swapping the plugs out was a huge improvement.
So I'll agree in the case where the old plugs are actually worn. Same could be said for a lot of things though. If your air filter is full of sand, putting a new one in would work wonders too.
