If radio noise appears after installing an MSD ignition, an MSD Noise Filter can help. Electro-magnetic interference (EMI) generated from MSD power cables is eliminated by installing the filter on the heavy power supply wires from the MSD, so the MSD draws current through the filter instead of directly from the battery — keeping other 12-volt accessories like the radio, fuel pump, or engine computer unaffected. The filter also protects the MSD during jump-starts and keeps the vehicle's 12-volt line clean of voltage and current surges that could interfere with accessories such as the Soft Touch Rev Control or Two Step Module Selector.
