Tachometer signal Filter.  High Energy Ignition System (HEI) and aftermarket compatible.

Provides a stable reliable signal to the Tachometer for better Tachometer response and performance.

This filter removes ignition spikes, voltage surges, electrical noise, causes by High Energy Ignition systems, and some after market ignition modules.
Compatible as an OEM replacement Tachometer filter for GM vehicles. Compatible with aftermarket ignitions systems such as MSD, Holley, Speedmaster.
Compatible with Tachometers that are circuit board driven (usually that would be 1975-1990 GM vehicles). Not compatible with Tachometers that are simply a coil.

Erratic and non-functioning tachometers can be caused by a faulty tachometer signal filter.

Three color-coded wires allow fast and easy fool-proof installation. Provides protection and superior response on all Classic Tachometers.

Includes installation hardware, installation instructions, and trouble shooting tips.
