If you experience radio noise after installing the MSD Ignition you may need to install an MSD noise filter. Electro magnetic interference EMI is occasionally generated from the MSD power cables and can be easily eliminated by installing the noise filter on the heavy power supply wires coming from the MSD. When the MSD draws current it will draw through the noise filter instead of directly from the battery so all other accessories that operate off 12 V like the radio fuel pump or the engine computer will be unaffected by the MSD. The noise filter will also prevent damage to the MSD during jump-starts and will keep a vehicles 12 Volt line clean by removing any voltage and current surges that could interfere with the operation of some MSD accessories such as the soft touch rev control or the two step module selector. It is recommended that the noise filter be used on installations with the MSD 7 and 8 series IGBTtiming to prevent this interference.
