I don't think it has a coil pack on an Aero model?
Had a look through some Aero pics of mine and it looks like the coils are individually located on each spark plug rather than HT leads connecting to a remote coil, if they all attach to a loom with a plug though - that could be disconnected and would have the desired effect..unless the ECU refuses to fire as it notes the fault.
Unfortunately my Aero is in bed at the moment, so I haven't had a play around in a while!
