Similar to the Boss or CJ they will loose some bottom end but pick up peak power in a n/a application, in a S/C application they will pick up everywhere.
The MMR intake works with all stock size injectors (ie Moran, Bilet atomizer, FAST injectors, Boshe etc) If the injectors you mention are the same as the stock size they will go right in, if not just let us know when you order the manifold and we can build it to fit for no extra charge.
