Finally, for the first time in years, Tach Filters are back. Corvette Mods now offers a direct replacement for the OE unit that protects your Corvette's tachometer circuits from damage.
Simply disconnect your old Tach Filter and install the new unit. For your convenience, our unit also comes with longer wire leads for easy installation. Also fits many other GM vehicles too. Instruction sheet included. The Tach Filter is located near the base of distributor on drivers side on C3 and behind distributor on passenger side on C4.
