The emu can only drive one passive coil per output and one VAG active coil per output. I recommend Bosch or Ford coilpack. If there is 8 passive on the Audi i recommend installing external amplifiers. Hüco 13 8055.

You can connect passive coils in parallel.
Or in the case of the VAG coil, when you connect them parralel you need to add pullup about 1K between 12V and ignition output

You can use these coils. Just connect them in parallel (2 to 1 output).
