I find these puppies quite an exciting prospect. Extra horsepower, torque and fuel economy (up to 10% of each) just by replacing your spark plugs with these US$25 pulse plugs that operate at 20,000x the wattage, causing quicker and fuller ignition. If what they say is true, this is the cheapest and most effective engine performance mod you can make. http://gizmag.com/go/7594/ Can anyone point out where their arguments are weak or false? From what the tests say I'd love to put these in my vehicles.
