These tachometer signal filters from New Vintage USA are compact and easy to install between the tachometer and the tachometer signal source, which is usually the coil. Signal filters are designed to eliminate the signal noise and surges that are generally caused by the ignition system. These tachometer signal filters help to modify the sharp up and down spikes into a semi-square wave signal for fast pointer response and steady pointer readings.
