I just checked CAPS for the coil #s on the Montero 3.0L SOHC and the Diamante 3.0L SOHC. The coils look identical, but have different part numbers:

MD131711 = Montero
MD166146 = Diamante

Mitsubishi still shows both part #s available, yet the Beck-Arnley catalog shows the same coil for both vehicles.

I have a Diamante coil - I might try it on the chance that it was an upgraded piece.... maybe it generates a better spark for the heat range 6 plugs.
