Longacre 44410 - AccuTech 'Stepper Motor' Tachometer Filter

The tach filter prevents erratic gauge operation by filtering out dirty electrical interference form selected hi-power ignition systems.

Installing a tach filter will clean up the noisy/dirty signal and therefore smooth out the reading on the gauge.

Filter for use with AccuTech™ SMi™ and DLi™ memory tachometers.
