You may be surprised what you can find at RockAuto
113309 is a Ferrari specific part (not a Bosch part). See post #47 in this thread for smg2's possible option.
Nick has made them available to buy direct from the printer. Keep in mind I don't set pricing, just the engineering dept. https://www.shapeways.com/product/ZKSE2ZDQR/ferrari-qv-cis-bushing?optionId=243556342&li=marketplace
I just saw this but don't have time to look right now. Pretty sure I got them for Ferrari but may have found them under Volvo.
Similar to what Mercedes and I think VW was a shrouded sleeve that used an air channel to control the injector atomization, but those will not fit to the Ferrari runners. The early 2V does share an injector design with,Saab, Volvo and VW for the threaded adapter. But the later QV is unique to Ferrari.
