IIRC some race cars had the injectors above a throttle body for each cylinder, with almost no intake runners. [citation needed]
For multi-point injection like this particular car, intake runners are the preferred location. The LPG injectors are mounted on holes, drilled on the runners before the petrol injectors (i.e. closer to the plenum), as close as possible to them to minimize injection timing issues. The LPG controller ECU uses the vehicle's ECU injector signals as a template.

Single point injection ones used to use throttle body I think.
