The 0439505009 have more flow capability, but swapping them in place of 0439505017 will not allow for more flow on a US (aluminum) fuel distributor. The injectors have no metering function. The fuel quantity is controlled only by the barrel slits in the fuel distributor, and the differential pressure across them.

There is an air shrouded K-Jetronic injector that has better atomization. VW and Audi used them. Not easy to adapt to a Porsche though.
