      Description


      Installed between the tachometer and the ignition trigger source (usually the coil), this filter traps, redirects, and dissipates the high voltage spikes and surges that are emitted by any late-model high-energy ignition system. Also modifies the sharp up-and-down spikes into a semi-square wave signal for steady pointer readings and faster pointer response. Three color-coded wires allow fast and easy fool-proof connections for life-time protection and superior response on all classic tachometers.
