I'm not sure but on yt i seen this mans conversion spark plugs for hho gas . This is the seaparation of water hydrogen and water oxygen . The spark plug in my opinion DOES NOT WORK ELETRICALLY , IT IS FREQUINCY ! I am sure the pressure causes a piece in the plug to vibrate and cause high frictional heat ! The war on fuel is a proxy hoax for the gov to take 3rd world native land and resources !
