It suppresses ignition noises from sparks. Resistor spark plugs prevent electrical interference that can disrupt car radio reception, two-way radio and cellular phone operation. This type of spark plug also prevents electrical noise from interfering with the operation of the computer in the engine. 1  Noise suppression effects of a resistor spark plug. (Compared with one of our conventional types) 2  As shown above, noise is reduced in all frequency zones by installing resistor spark plugs.
This is the first time we have taken a comprehensive view of mental illness on its own.. Estimates of mental illness -- such as major depressive disorder and other mental health problems -- were made based on data from the 2009 National Survey on Drug Use and Health, which polls about 68,700 Americans ages 12 and up.
