OEM injectors are pintle design; good for its time, but there have been many generational iterations of fuel injectors since.

Recently BMW aligned with Bosch to release a direct replacement 14.5lb gen 3 injector that is 4 hole (disc type).

4 hole injectors provide for much better fuel atomization when compared to pintle design; responsiveness and fuel economy should be expected improvements.
