this is what it says in vw golf+ mag
"its a new range of spark plugs are so new that they are yet to be advertised at the the time of going to press! new pulsar pulse plugs are made in the USA and are ten times more powerful than standard plugs. energy from the engine's power coil is stored and in the built in capacitor of the pulsar plug.
At the exact moment needed, that the energy is released in a amazingly quick (two nanoseconds!) high energy pulse. These pulses ignite the fuel sooner and more thoroughly, therefore increasing internal cylinder pressure by as much as 10%. The result is an increase in power and torque as the company has proven on the rollers (there is a picture of the dyno print out!) with a mk4 golf 1.8T GTi posting a very healthy 10.8bhp increase!"
