Brand new OEM Mazda genuine part There are several different coil pack configurations on 94-97 Miatas with the difference lying in the connectors. 1994 to 1995 1/2 had four pins (due to the presence of a tach signal wire) and 1995 1/2 to 1997 had three pins (due to the lack of the tach signal wire). The tach signal wire was dropped when the ECU's went to OBDII. The sure way to check to see what coil pack you need is to check the wiring going into the coil pack connectors. If it has 3-wires, it's a later model (not this one). If it has 4 wires, you need this one.
