Am I right to say that the 94 WRX engine has its own seperate ignition module? As Im running the Microtech LT-10s it would have been setup to comply with my seperate coil packs. I ask this as thinking of getting either the Bosch GT40 coil packs or the Microtech twin coils and then having leads made up. Microtech coils look neater as they are twins instead of 4 seperate coils. Either way would cut the old harness plug from the Suby coils and wire them to the new coils so can still unplug easily.
